A car moves at a constant speed on a road as shown in figure. The normal force by the road on the car is `N_A and N_B` when it is at the points A and B respectively
.

Options

A. `R_(A) gt R_(B)`
B. `R_(A) lt R_(B)`
C. `R_(A)=R_(B)`
D. `R_(A)=R_(B)=0`

Answer

B

Explanation

At 'A'.,`R_(A)=mg-(mv^(2))/(r_(A))`
At'B',.`R_(B)=mg-(mv^(2))/(r_(B))`.
`as, r_(B)gtr_(A)`
we get, `R_(A)ltR_(B)`.
