Question

solve this plz physics question step by step explanation​

Answer 1

when it will complete half tha circle the distance will be half the perimeter of circle which is πr

the displacement in this case will be path from intial to final that is 2r

where r is radius of circle

In second case distance will be the whole perimeter of circle which is 2πr

for displacement it came back on the same position so displacement will be zero

HOPE IT HELPS BRU

Answer 2

Answer: i) 22/7  ii)2Pi.r

Explanation: i) 2Pi.r/2 = Pi = 22/7

                      ii) as it complete whole circle it will be 2Pi.r
