Questions
A particle of mass kg is moving in a circular path of radius 1 m. Speed of the particle is increasing at a rate . Then the force acting on the particle when its speed is is
detailed solution
Correct option is A
Centripetal acceleration, an=V2r=(1)21ms2=1 ms2Tangential acceleration, at=1 ms2Total acceleration, a=an2+at2=12+12ms2=2 ms2∴ Force, F=ma=2×2 N=2 NTalk to our academic expert!
