What is the magnitude and direction of the force in the diagram? *
Answers
Step-by-step explanation:
(a) As the raindrop is falling with a constant speed, its acceleration, a=0. Hence net force F=ma=0.
(b) As the cork is floating on water, its weight is balanced by the upthrust due to water. Therefore, the net force on the cork is 0.
(c) As the kite is held stationary, in accordance with the first law of motion, the net force on the kite is 0.
(d) Force is being applied to overcome the force of friction. But as the velocity of the car is constant, its acceleration, a=0. Hence net force on the car F=ma=0.
(e) As the high-speed electron in space is far away from all gravitating objects and free of electric and magnetic fields, the net force on the electron is 0.
Answer:
Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of force. By resolving force →F into two components : (i) F cosθ in the direction of displacement of the body. (ii) F sinθ in the perpendicular direction of displacement of the body.
