An object traveling a circular path of radius 5 m at constant speed experiences an acceleration of 3 m/s2. if the radius of its path

is increased to 10 m, but its speed remains the same, what is its acceleration?

0.3 m/s2

1.5 m/s2

6 m/s

12 m/s2

Option B is the correct answer.

Explanation:

In circular motion we have

An object traveling a circular path of radius 5 m at constant speed experiences an acceleration of 3 m/s². We need to find acceleration when radius is 10 m with same speed.

That is here the radius is doubled, we need to find what will happen to acceleration.

Dividing both equations,

Option B is the correct answer.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
