Question

3. A body is notating in a circular path of radius 10 cm has time
period 10s. What is the displacément of the body after 25sec​

Answer 1

Answer:

Total displacement is 20cm

Explanation:

According to ques, for complete rotation of circle the displacement is zero.

So, in 20 sec of time interval it cover 2 round completely so their displacement is zero.

In last 5 sec it complete half circle

So their minimum distance will be 2× radius

Therefore,, 2r = 2×10

= 20 cm
