Question:medium
In case of well of death which is a vertical cylindrical wall of radius ' \(r\) ' inside which vehicle is driven in horizontal circles. If ' \(m\) ' is mass of vehicle, ' \(V\) ' is the velocity and ' \(\mu_s\) ' is the coefficient of static friction between the wheels of vehicle and walls then correct relation is [ \(g\) = acceleration due to gravity]

- \(V^2 \le \frac{rg}{\mu_s}\)
- \(V \le \frac{rg}{\mu_s}\)
- \(V^2 \ge \frac{rg}{\mu_s}\)
- \(V \ge \frac{rg}{\mu_s}\)
Show Solution
The Correct Option is C
