What is the magnitude of average velocity after half rotation, if a particle is moving with
constant speed 
in a circle?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The time taken to cover the complete circle would be equal to 
,
Hence the time taken to cover half the rotation would be equal to 
.
Hence the magnitude of average velocity after half rotation would be equal to
