A particle of mass `m` oscillates inside a smooth spherical shell of radius `R` and starts its motion from point `B`. At given instant the kinetic energy of the particle is `K`. Then the force applied by particle on the shell at this instant is `:-`

A particle of mass m oscillates along the horizontal diameter AB inside a smooth spherical shell of radius R . At any instant K.E. of the partical is K . Then force applied by particle on the shell at this instant is:

A partical of mass m oscillates along the horizontal diameter AB inside a smooth spherical AB inside a smooth sperical shell of radius R . At any instate K.E. of the partical is K . Then force applied by partical on the on the shell at this instant is:

A partical of mass m oscillates along the horizontal diameter AB inside a smooth spherical AB inside a smooth sperical shell of radius R . At any instate K.E. of the partical is K . Then force applied by partical on the on the shell at this instant is:

A particle of mass m is located inside a spherical shell of mass M and radius R. The gravitational force of attraction between them is

A particle of mass m oscillates inside the smooth surface a fixed pipe of radius R . The axis of the pipe is horizontal and the particle moves from B to A and back. At an instant the kinetic energy of the particle is K (say at position of the particle shown in figure ). Then choose the correct value of force applied by particle on the pipe at this instant.
