1.

Give the magnitude and direction of the net force acting on1. a kite skillfully held stationary in the sky. 2. a car moving with a constant velocity of 30 km/h on a rough road. 3. a high-speed electron in space far from ail material objects, and free of electric and magnetic fields.

Answer»

1. Since the kite is in the state of rest net force on it is zero. 

2. From the first law of motion, since the velocity of the car is a constant net force on it is zero. 

3. Since the electron is in free space no gravitational or electric or magnetic force is acting on it. Hence net force on it is zero.
