A particle is moving along a circular path of radius of `R` such that radial acceleration of particle is proportional to `t^(2)` then

Options

A. Speed of particle is constant
B. Magnitude of tangential acceleration of particle is constant
C. Speed of particle is proportional to time
D. Magnitude of tangential acceleration is variable

Answer

B, C

Explanation

`a_(r)alpha t^(2),v^(2)=krt^(2),v=sqrt(kr)t`
`(dv)/(dt)=sqrt(kr)="constant"`
