A small ring is rolling without slipping on the circumference of a large bowl as shown in the figure. The ring is moving down at `P_(1)`, comes down to the lower most point `P_(2)` and is climbing up at `P_(3)`. Let `vecv_(CM)` denote the velocity of the centre of mass of the ring. Choose the correct statement regarding the frictional force on the ring.img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/KVPY_CP_XII_P1_2017_PHY_E01_016_Q01.png" width="80%"
