List all the forces acting on the blcok B in figure

Power due to a force actoing on a block varies with time t as shown in figure. Then angle between force acting on the block and its velocity is :-

A metal sphere is a string fixed to a wall. The forces acting on the sphere are shown in figure. Which of following statements are correct.

A block is placed on the horizontal surface. There are two forces acting on the block. One, the downward pull of gravity and other a normal force acting on it. Are these forces equal and opposite? Do they form action - reaction pair? Discuss with your friends.

There are three forces F_(1) F_(2) and F_(3) acting on a body, all acting on a point P on the body. The body is found to move with uniform speed. (a) Show that the forces are coplanar. (b) Show that the torque acting on the body about any point due to these three forces is zero.

Discuss the forces acting on the n particles in a system.

What is the force acting on electric dipole in uniform electric field ?

For body of 50 kg. mass, the velocity time graph is shown in figure. Then force acting on the body is :-

Figure shows the displacement of a particle going along the X-axis as a function of time. The force acting on the particle is zero in the region

A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force. Let us take it that the force acts on the object through the displacement. What is the work done in this case?
