Question

The relation `tan theta = v^(2)// r g` gives the angle of banking of the cyclist going round the curve . Here `v` is the speed of the cyclist , `r` is the radius of the curve , and `g` is the acceleration due to gravity . Which of the following statements about the relation is true ?
A. both dimensionally and numerically correct
B. neithen numerically not dimensionally correct
C. dimensionally correct only
D. numerically correct only

Answer 1

Correct Answer - c
Given equation is dimension correct because both sides are dimensionaless but numerically wrong because the correct equation is `tan theta = (v^(2))/(rg)`
