N bullets each of mass \(m\,\mathrm{kg}\) are fired with a velocity \(v \ \mathrm{m\,s}^{-1}\) at the rate of n bullets per second upon a wall. The reaction offered by the wall to the bullets is given by
\((a) nmv (b) \frac{\mathrm{Nmv}}{n} (c) n \frac{\mathrm{Nm}}{v} (d) n \frac{\mathrm{Nv}}{m}\)
Text Solution
Verified by ExpertsThe correct answer is:
A
Total mass of bullets = Nm, time \(t = \frac{N}{n}\)
Momentum of the bullets striking the wall = Nmv
Rate of change of momentum (Force) = \overline{N_{lmv}} \\ t = nmv.
