Solution

The correct option is A P
Resistance offered by plank, F = ma
So, F is directly proportional to m
So, less is mass, less resistance, more penetration.
So, P will penetrate more.

Q. A bullet is fired on a fixed target. It penetrates inside the target through distance

d = 3.75

cm and then stops, mass of the bullet is

m = 1

kg and of the target is

M = 4

kg. Now an identical bullet moving with the same velocity is fired on the identical target which is placed at rest on a frictionless horizontal surface. Then find the distance (in cm) to which the bullet will penetrate inside the target?
