Answer:
Static electric field lines begins with
The field line begins at the charge and ends either at the charge or at infinity. When the field is stronger, the field lines are closer to each other.
The first law of Kirchhoff's is based on charge conservation.
force acting on a moving charge in a magnetic field is known as Lorentz force.
Magnetic fields exert forces on moving charges. The direction of the magnetic force on a moving charge is perpendicular to the plane formed by v and B and follows right hand rule–1 (RHR-1). The magnitude of the force is proportional to q, v, B, and the sine of the angle between v and B.
The emf induced in a circuit is proportional to the time rate of change of the magnetic flux linking that circuit.
In an electrical circuit R, L, C and an a.c.voltage source are all connected in series. When L is removed from the circuit, the phase difference between the voltage and the currentin the circuit is π/3.
Radio waves, x-rays, and visible light waves come under EM waves category. Hence they can be polarized.
While the size of the image is greater than the object, the angular size of the image is equal to the angular size of the object. A magnifying glass allows one to see objects that are closer than the least width with a distinct vision. A closer object has a greater angular measurement.
Answer:
1.with positive cahrge
