Question

7.A particle moves with a constant angular acceleration a in a circular path. The time at w PHYSI
magnitudes of tangential and radial accelerations are equal is
CIRCULAR MOTION
A)1/A
B)RATIO OF A
C)1/RATIO A
D)A
​

Answer 1

Answer:

Given that Constant angular acceleration =α

We know that

ω=ω

0

+αt

Here ω

0

=0

ω=αt

r

v

=αt

v=αtr

Now tangential acceleration = centripetal acceleration

αr=

r

v

2

αr=

r

α

2

t

2

r

2

t=

α
