If the momentum of a body increases by 0.01%, its kinetic energy will increase by

A

0.0008

B

0.0002

C

0.0004

D

0.0001

Text Solution

Verified by Experts

The correct Answer is:
B
The resultant force acting on the body is
`R=sqrt(4^2+3^2)=5N`
`:.` Acceleration a=`F/m=5/(10)=1/2m//s^2`
`:.` The velocity of the body at the end of 10s is
`v=u+at=0+1/2xx10=5m//s`
`:.` The K.E. of the body=`1/2mv^2`
`/2xx10xx25=125J`
