Figure shows a boy pulling a wagon on a road.
List as many forces as you can which are relevant with this figure. Find the pairs of forces connected by Newton's third law of motion.

Consider a block suspended from a light string as shown in the digure. Which of the following pairs of forces constitute Newton's third law pair ?

Three boys are pushing horizontally a box placed on horizontal table. One is pushing towards north with a 5sqrt(3) N force. The second is pushing towards east and third pushes with a force 10 N such that the box is in equilibrium. Find the magnitude of the force, second by is applying in newton.

Three ant P,Q and R are pulling a grain with forces of magnitude 6N,3sqrt(3) N " and " 3sqrt(2)N as shown in the figure. Find the magnitude of resultant force (in N ) acting on the grain .

A 100gm ball moving horizontally with 20m/s is struck by a bat, as a result it starts moving with a speed of 35m/s at an angle of 37 above the horizontal in the same verticle plane as shown in the figure. ltb/rgt (a) Find the average force exerted by the bat if duration of impact is 0.30s.ltb/rgt (b) FInd the average force exerted by the bat if duration of impact is 0.03s. (c) Find the average force exerted by the bat if duration of impact is 0.003s. (d) What do you conclude for impulse of weight of the ball as duration of contact decreases?

Figure shows a rigid rod of length 1.0 m. It is pivoted at O. For what value m, the rod will be in equilibrium ? Find the force (F) exerted on the rod by the pivot. Neglect the weight of the rod.

The figure shows a particle (carrying charge +q) at the orgin. A uniform magnetic field is directed into the plane of the paper. The particle can be projected only in the plane of paper and along positive or negative x- or y-axis. The particle moves with constant speed and has to hit a target located in the third quadrant. There are two direction of projections, which can make it possible, these are

Two forces act on a particle simultaneously as shown in the figure. Find net force in milli newton on the particle. [Dyne is the CGS unit of forces ]

There are four forces acting at a point P produced by strings as shown in figure. Which is at rest ? Find the forces F_(1) and F_(2) .

A heavy cart is pulled by a constant force F along a horizontal track with the help of a rope that passes over a fixed pulley, as shown in the figure. Assume the tension in the rope and the frictional forces on the cart remain constant and consider motion of the cart until it reaches vertically below the pulley. As the cart moves to the right, its acceleration
