A 500 kg car takes a round turn of radius 50 m with a velocity of 36 km/hr . The centripetal force is

Options

A. 250N
B. 750N
C. 1000N
D. 1200N

Answer

C

Explanation

The centripetal force required for a car (mass m) to take a sharp turn of radius r with velocity v is `F=(mv)^(2)/(F)`
Given, m=500g
`v=36km//h=36xx(5)/(18)=10m//s,r=50m`
Hence, `F=(500xx(10)^(2))/(50)=1000N`
