Question

A body is moving in a circular path with acceleration a. If its velocity gets doubled then find

the ratio of acceleration after and before the change of velocity ?

Answer 1

Heya...

Here's your answer....

when an object moves in circular path with constant speed

then it acceleration is given as

a = v²/R

now we have

a₁ = v²/R

when speed is doubled then acceleration is given as

a₂ = (2v)²/R

a₂ = 4v²/R

now the ratio of final and initial acceleration will be

a₂/a₁= 4v²/R / v²/R

so it will be

a₂/a₁

so the ratio of acceleration will be 4 : 1
