Question

Describe the nature of path followed by the particle in both the cases

• A. parabola
• B. circle
• C. straight line
• D. can't say

Answer 1

Answer: (B)

circle

The particle moves in $+\hat{j}$ direction and force on it acts in $\hat{j}\times \hat{i}=-\hat{k}$ direction which is perpendicular to the direction of velocity.

This force provides the centripetal acceleration and the particle follows a circular path.
