Discuss about force on a moving charge.
Answers
Right hand rule 1
Magnetic force on one moving charge is one of the most fundamentals well-known. The magnetic force is significant as the electrostatic or covalent force. Nonetheless, the magnetic force is more multifaceted in contrast to the comparatively simple Coulomb force, both the number of factors and its direction. In the magnetic field of Strength B, the magnitude of the magnetic force F is given on the charge Q running at V speed.
F = QVB sin θ,
Where θ is an angle between the directions of V and B. This force is often called the Lorentz force. Basically, in this way we define the power B of the magnetic field in terms of force on the charged particle running in a magnetic field. For the power of the magnetic field, the SI unit is called Tesla (T) after the singular but spectacular inventor Nikola Tesla (1856-19 43). To determine how Tesla relates to other SI units, we solve F = QVB sin θ for B.
B = FqvsinθB = Fqvsinθ
Because sin θ is unit less, it is tesla
1 T = 1 N / ca M / s
= 1 NA⋅ M1
(Note that C / S = A). Another small unit called Gauss (G), where 1G = 10-4 T, is sometimes used. The strongest permanent magnet has area near 2T; Superconducting electromagnets can achieve 10 T or more. The Earth's magnetic field on its surface is only 5 × 10-5 T, or 0.5 g.
The direction of magnetic force F is perpendicular to the plane formed by V and B, as the right hand is determined by rule 1 (or RHR-1), which is shown in Figure 1. RHR-1 says that to determine the direction of the magnetic force on a positive moving charge, you point to the right thumb in the direction of V, the fingers in the direction of the B, and the palm in the direction of F is perpendicular to the points Are there. One way to remember it is that there is a velocity, and therefore thumb represents it. There are many field lines, and therefore fingers represent them. The force is in the direction that you will press with your palm. The force on a negative charge is in the opposite direction on the positive charge.

Force➫ Any interaction that when unopposed will change the motion of an object.
♦ It's SI unit is Newton (N).
♦ It has both magnitude & direction, making it a vector quantity.
♦ It can cause an object with mass to change its velocity to accelerate.
➊❭ Effects 0f Force are:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❱ It can make a stationary object move or change its position of rest.
♦Ex:- When you kick a stationary Football it will in motion.
❱ It can change the speed of a moving object.
♦Ex:- When goalkeeper applies force to stop the football.
❱ It can change the direction of motion of a moving object.
♦Ex:- When a batsman hits a ball.
❱ It can change the shape or size of an object.
♦Ex:- When you squeeze a sponge.
❷❭ Types 0f Force are:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❲1❳ Contact Force➫ A force that acts only when it is in contact with an object.
♦Ex:- Pushing a car up a hill.
❱ Types 0f Contact Force:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❱ Muscular➾ The force which is exerted by the muscle of your body.
♦Ex:- When you lift your School's Bag.
❱ Frictional➾ The force generated by two surfaces that contacts & slide against each other.
♦Ex:- A person sliding down a slide.
❲2❳ Non-Contact Force➫ A force that acts on an object without being in contact with it.
♦Ex:- Leaves falling from a tree.
❱ Types 0f Non-Contact Force:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❱ Gravitational➾ A force that attracts any two objects with mass.
♦Ex:- Leaves falling from trees.
❱ Magnetic➾ The force that arises due to the motion of charged particle within the magnetic field.
♦Ex:- Iron pin attracted to magnet.
❱ Electrostatic➾ The attraction or repulsion of particles or objects because of their electric charge.
♦Ex:- When you rub a comb in hair.
