JEE Main 6 April 2023, Shift 2, Physics Q32

Question 32 of 90 in this shift, Physics question 2 of 30, Section A.

As shown in the figure, a particle is moving with constant speed π\pi m/s. Considering its motion from A to B, the magnitude of the average velocity is:

The figure, in words

Circle with centre marked; A is on the horizontal radius to the right with velocity V pointing up; B is on the circle with velocity V pointing up-left; the angle between radii to A and B is 120 degrees.
  1. (1)π\pi m/s
