A train is moving with a speed of 12 m/s12 \mathrm{~m} / \mathrm{s} on rails which are 1.5 m1.5 \mathrm{~m} apart. To negotiate a curve of radius 400 m,400 \mathrm{~m}, the height by which the outer rail should be raised with respect to the inner rail is (Given g=10 m/s2)\text{(Given } g=10 \mathrm{~m} / \mathrm{s}^2)
View answer and explanation
Correct option: D
5.4 cm5.4 \mathrm{~cm}
Option D (5.4 cm) is correct because it is calculated using the banking angle formula relating velocity, radius, and the distance between the rails.
