The shaft of an electric motor starts from rest, and on the application of a torque, it gains an angular acceleration of 
during the first two seconds after it starts, after that, 
. Calculate the angular velocity after 6 seconds.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Given, 
Since there is no angular acceleration after 2 s. the angular velocity after 6 s remains the same, i.e., 
.
