A car goes on a horizontal circular road...

A car goes on a horizontal circular road of radius R, the speed increasing at a constant rate `(dv)/(dt)=a`. The friction coefficient between the road and the tyre is `mu`. Find the speed at which the car will skid.

A

`[(mu^(2)g^(2) - a^(2))R^(2)]^(1/4)`

B

`[(mu^(2)g^(2) + a^(2))R^(2)]^(1/4)`

C

`sqrt(mu gR)`

D

`sqrt(aR)`
