A car is moving on a circular path and takes a turn. If `R_(1)` and `R_(2)` be the reactions on the inner and outer wheels, respectively, then

A

`R_(1) = R_(2) `

B

`R_(1) lt R_(2)`

C

`R_(1) gt R_(2)`

D

`R_(1) ge R_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Suppose that a car of mass M is moving in a circular path of radius r, with a speed v.
h= height of the centre of gravity of the from the road level 2a = distance between the centres of the wheels of the car Let `R_(1 ) and R_(2)` are given by
`R_(1) =1/2 M[g-(v^2h)/(ra)]`
`R_(2) = 1/2M[g+(v^2h)/(ra)]`
thus we find than ` R_(1) lt R_(2)`
Note: When the speed increases beyond a certain limit the car overturns and its inner wheel leaves the ground first .
