A particle is moving along a circle of radius R with a uniform speed v. At t=0,the principal is moving along east. Find the charge in velocity (magnitude and direction)in (a) 1/4 Revolution,(b) 1/2revolution(c)3/4 Revolution and (d)1revolution

Let the particle start at t=0 at origin of cartesian coordinate system.
Velcoity vectors are shown in figure for each quarter revolution.
Change in velocity after 1/4 revolution = v1 - vo = |v| ( j - i )
Change in velocity after 1/2 revolution = v2 - vo = -2|v| i
Change in velocity after 3/4 revolution = v3 - vo = -|v| ( j + i )
Change in velocity after 1 revolution = 0
