A point object moves on a circular path such that distance covered
by it is given by function [IMAGE] meter (t in second).
The ratio of the magnitude of tangential and radial acceleration at t =
2 sec. is 1: 2 then radius of the circle is ( in meter )

[IMAGE] (t ) t = 2 sec.
1:2

Show answer and solution

S = [IMAGE] + 2t
v = t + 2
[IMAGE] R = 8 m
