Question:medium
A body of mass 3 kg is kept on a rough horizontal surface. A horizontal force of 20 N acting on the body produces an acceleration of $4 ms^{-2}$ in the body. To double the acceleration of the body, the horizontal force applied is to be increased by

Show Hint
Be careful! Doubling the acceleration does {not} imply doubling the applied force when friction is involved. It doubles the {net} force. Always solve for the friction first.
