Question

State whether true or false.

If the same force is applied on two bodies of different masses for the same time, then the change produced in the momentum of the two bodies is also the same.

• A. True
• B. False

Answer 1

The correct option is A True

Let A and B be two bodies and F be the force for t time duration.

$a_A=\frac{F}{M_A}$ ,$a_B=\frac{F}{M_B}$

$V_A$ (after t)$=\frac{F_t}{M_A}$

$V_B$ (after t)$=\frac{F_t}{M_B}$

Momentum of A $=M_A{V}_A=Ft$

Momentum of B $=M_B{V}_B=Ft$
