Two forces of equal magnitude F act on two isolated bodies P and Q as shown in the figure. The mass of body Q is three times that of body P. The magnitude of the acceleration of P is

A

Three times that of Q

B

(1/3) that of Q

C

Nine times that of Q

D

(1/9) that of Q.

Text Solution

Verified by Experts

The correct Answer is:
A
Let the mass of body P = m
the mass of body Q = 3m
As, force acts on P = force acts on Q , `F_P = F_Q`
or `ma_P=3ma_Q therefore a_p=3a_Q`
[Here `a_P` and `a_Q` are accelerations of P and Q respectively]
