Question

On a horizontal curved road, the maximum safe speed of a vehicle to move along the road without overturning is
(where mu is the coefficient of friction)
A. `v=mu rg`
B. `v=sqrt( mu rg)`
C. `v=sqrt((mu)/(rg))`
D. `v=sqrt((rg)/(mu))`

Answer 1

Correct Answer - B
Centripetal force =Force of friction
`therefore (mv^(2))/(r)=mu mg`
` therefore v=sqrtmu r g`
