Question

Two particles of masses m and m/2 are moving along the circular paths of radii r and 3r, respectively, with equal speed. What is the ratio of their accelerations? 1 point a) 1 : 1 b) 1 : 3 c) 3 : 1 d) 2 : 1​

Answer 1

Answer:

r

1

: r

2

Since both make complete circles in same time 't'. so angular velocity is also same for both the masses.

since centripetal acceleration a=ω

2

r

so

a

a

1

=

ω

2

r

ω

r

1

and ω

1

=ω

2

so

a

a

1

=

r
