JEE Main 2023 — Mathematics in Physics Question with Solution

JEE Main 2023 (31 Jan Shift 2)

Question

A body is moving with constant speed, in a circle of radius 10 m. The body completes one revolution in 4 s. At the end of 3rd second, the displacement of body (in m) from its starting point is:

Correct answer
D102

Step-by-step explanation

Give: r=10 m, T=4 s.

Displacement is defined to be the change in position of an object. As we can see from the above figure, displacement will be d=r2+r2

⇒d=102 m
