Solution

The correct option is A $\frac{M n}{60}$
no of discs striking per second is = $\frac{n}{60}$
so force on wall = $\frac{n * M}{60}$
so the answer is A.

Q. A scattering experiment is done with a 32 kg disc and two 8 kg discs on a frictionless surface. In the initial state of the experiment, the heavier disc moves in the x direction with velocity v = 25 m/s toward the lighter discs, which are at rest. The discs collide elastically. In the final state, the heavy disc is at rest and the two smaller discs scatter outward with the same speed. What is the x -component of the velocity of each of the 8 kg discs in the final state?

A number of discs, each of momentum 'M' kg m/s are striking a wall at the rate of n discs per minute. The force associated with these discs, in newtons, would be

The correct option is A Mn60no of discs striking per second is = n60so force on wall = n∗M60so the answer is A.

The correct option is A $\frac{M n}{60}$
no of discs striking per second is = $\frac{n}{60}$
so force on wall = $\frac{n * M}{60}$
so the answer is A.
