A small body slips, subject to the force of friction, from point $A$ to point $B$ along two curved surfaces of equal radius, first along route $1,$ then along route $2$. Friction does not depend on the speed and the coefficient of friction on both routes is the same. In which case will the body’s speed at $B$ be greater?

816-145

  • A

    speed is greater in case $1$

  • B

    speed is greater in case $2$

  • C

    speed is same in both cases

  • D

    cannot be determined
