Give the magnitude and direction of the net force acting on a high-speed electron in space far from all gravitating objects, and free of electric and magnetic field?

The net force acting on the high speed electron is zero because there is not field (gravitational, electric or magnetic) acting on the electron.

Give the magnitude and direction of the net force acting on a drop of rain falling down with constant speed.

As the raindrop is falling with a constant speed, acceleration = 0. Hence, net force ma= 0.

Give the magnitude and direction of a car moving with constant speed on rough road.

Given, the velocity with which the car is moving is constant. So, acceleration=0. Hence, net force on the car is zero.

# Give the magnitude and direction of the net force action on a high-speed electron in space far from all material objects, and free of electric and magnetic fields.

Given that, no field is acting on the electron. Therefore, net force on the particle is equal to zero.
