Question 298: Work, Energy and Power & Circular Motion

Question

The angle of banking '$$	heta$$' for a meter gauge railway line is given by $$	heta=	an ^{-1}\left(\frac{1}{20}ight)$$. What is the elevation of the outer rail above the inner rail?

Accepted Answer

$$	an	heta=\frac{1}{20}=\frac{h}{1}$$
$$	herefore \mathrm{h=\frac{1}{20}m=0.05m=5cm}$$

Answer

$$20 \mathrm{~cm}$$

Answer

$$10 \mathrm{~cm}$$

Answer

$$0.2 \mathrm{~cm}$$

Answer

$$5 \mathrm{~cm}$$
