The figure shows th velocity and acceleration of a point like body at the initial moment of its motion. The acceleration vector of the body remain constant. The minimum radius of curvature of trajectory of the body is

Options

A. `2 meter`
B. `4 meter`
C. `8 meter`
D. `16 meter`

Answer

D

Explanation

Acceleration vector shall change component of velocity `v costheta` along acceleration vector `r=v^(2)/a_(n)` `r` is min when it is min this is possible when component of velocity parallel to acceleration vector is zero i.e., `v_(0) cos theta=0`
