Force Test - 3...

In which of the following cases are the forces acting on the body balanced?

Two forces of 9 N and 6 N act on a body in downward direction, while another force of 15 N acts on the body in upward direction. What is the resultant of the forces?

Two children try to push a box on a rough floor. The sum of the forces applied by both of them is 7 N and the force of friction is 3N. Based on that, which of the following statements is correct?

A body of mass 200 g is resting on a frictionless table. What is the acceleration of the body, when it is acted upon by a force of 0.05 N?

A ball of mass 20 g is initially moving with a velocity of 25 ms^-1. On applying a constant force on the ball for 2 s, it acquires a velocity of 65 ms^-1. What is the magnitude of the force applied?

On applying a force of 2 N on masses m₁ and m_2, it produces acceleration of 5 ms^-2 and 10 ms^-2, respectively. Calculate the acceleration, when both the masses are tied together.

A force F1 is required for accelerating a 3 kg mass accelerating at the rate of ms-2 and a force F2 for a 6 kg mass at the rate of 2 ms-2.
Choose the correct option.

A force `F` is required to accelerate a body of mass `m` at 10 ms^-2. What is the force required to accelerate a body of mass `2m` at the rate of 20 ms^-2?
