A car of mass 1500 kg rounds a curve of radius 250 m , at 90 km / hour . What is the centripetal force acting on it ?

A

`2550N`

B

`3100N`

C

`3750 N`

D

`4200N`

Text Solution

Verified by Experts

The correct Answer is:
C
`V=90 km//h = (90xx1000)/(60xx60)=25 m//s`
[Remember 18 km/h = 5 m/s]
`therefore C.P "force" = (mv^2)/(r )=(1500xx25xx25)/(250) =3750 N`
