PhysicsEasysingle choice

A curved road of diameter $1.8 km$ is banked so that no friction is required at a speed of $30 {m s}^{- 1}$ . What is the banking angle?

Options:

Answer:

Solution:

As, $\tan θ = \frac{v^{2}}{r g}$

Where, $θ =$ the angle of banking.

$\Rightarrow \tan θ = \frac{30 \times 30}{10 \times 0.9 \times 10^{3}} = 0.1$

$\Rightarrow θ = \tan^{- 1} (0.1)$
