Question

A train is moving with a speed of 12m/s on rails which are 1.5m apart. To negotiate a curve radius 400m, the height by which the outer rail should be raised with respect to the inner rail is (Given, g=10m/s^2 ):

Accepted Answer

Correct answer: B. (b) tan = v^2 Rg= 12 1210 4001.5 m tan ⁡ = h1.5 ⇒ h1.5= 1444000 h=5.4 cm

$A train is moving with a speed of 12 m / s on rails which are 1.5 m apart. To negotiate a curve radius 400 m, the height by which the outer rail should be raised with respect to the inner rail is (Given, g = 10 m / s^{2}):$
