Question

If a force of $200N$ acts on a body. The momentum acquired is $100kg$ $m/s$. What is the period for which force acts on the body?

• A. $0.2$sec
• B. $0.5$ sec
• C. $0.4$ sec
• D. $0.25$ sec

Answer 1

The correct option is B $0.5$ sec

B. $0.5sec$

Given,

$F=200N$

$P=100m/s$

By second law of Newton, change in linear momentum with respect to the time is known as Force.

$F=\frac{P}{t}$.

$t=\frac{P}{F}=\frac{100}{200}$

$t=0.5sec$
