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 metre
B. 4 metre
C. 8 metre
D. 16 metre

Answer

B

Explanation

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