An electron of mass 9.1 x 10−31 kg moves with a speed of 2.0 x 106 ms−1 round the nucleus of an atom in a Circular path of radius 6.1 x 10(^{11}\) m. Determine the angular speed of the electron.
3.28 x 1016 rad s−1
8.55 x 103 rad s−1
9.11 x 1013 rad s−1
5.22 x 1015 rad s−1
Correct answer is A
Angular speed of the electron (W)
w = VelocityRadius=VR
= 2.0×1066.1×1011
= 3.28 x 1016 rads−1
