Physics Question from JEE Main 2025 · 24 January, Shift 1

A car of mass mm moves on a banked road having radius rr and banking angle θ\theta. To avoid slipping from the banked road, the maximum permissible speed of the car is v0v_0. The coefficient of friction μ\mu between the wheels of the car and the banked road is:

  • A

    μ=v02+rgtan⁡θrg−v02tan⁡θ\mu = \frac{v_0^2 + rg \tan \theta}{rg - v_0^2 \tan \theta}

  • B

    μ=v02+rgtan⁡θrg+v02tan⁡θ\mu = \frac{v_0^2 + rg \tan \theta}{rg + v_0^2 \tan \theta}

  • C

    μ=v02−rgtan⁡θrg+v02tan⁡θ\mu = \frac{v_0^2 - rg \tan \theta}{rg + v_0^2 \tan \theta}

  • D

    μ=v02−rgtan⁡θrg−v02tan⁡θ\mu = \frac{v_0^2 - rg \tan \theta}{rg - v_0^2 \tan \theta}
