Question

A body moving in a circle of radius R covers 3 upon 4 on the circle find the ratio the distance of displacement

Answer 1

HEY MATE HERE IS YOUR ANSWER PLEASE MARK ME AS A BRAINLIST ANSWER

Now as it cover 3/4 distance = 2πr / 3/4 
                                                 d = πr/2
displacement = d" =√( r²+r²)
                         d"=r√2
distance / displacement = πr / 2 r√2
                                       = π / 2√2 
= π :2√2 Ans
