Equilibrium of a Particle

A charged particle having some mass is resting in equilibrium at a height H above the centre of a uniformly charged non-conducting horizontal ring of radius R . The equilibrium of the particle will be stable .

A particle is at rest with respect to the wall of an inverted cone rotating with uniform angular velocity omwega about its central axis. The displacement of particle along the surface up or down, the equilibrium of particle is

A : The equilibrium of a charged particle under the action of electrostatic force alone can never be stable. R : Coulombian force is an action-reaction pair.

A block of mass 200 gm is suspended through a vertical spring. The spring is stretched by 1 cm when the block is in equilibrium. A particle of mass 120 gm is dropped on the block from a height of 45 cm. The particle sticks to the block after the impact. Find the maximum extension of the spring.

Two particle A & B each of mass m are in equilibrium in a vertical plane under action of a horizontal force F=mg on particle B, as shown in figure Then :

In the figure shown mass 2m is at rest and in equilibrium. A particle of mass m is released from height (4.5mg)/(k) from palte. The particle sticks to the plate. Neglecting the duration of collision. Starting form the when the particles sticks to plate to the time when the spring is in maximum compression for the first time is 2pisqrt((m)/(ak)) then find a .

Three forces of magnitude 30, 60 and P Newton acting on a particle and particle is in equilibrium. If the angle between the first two forces is 60^(@) , the value of P is

When force vec(F)_(1),vec(F)_(2),vec(F)_(3) are acting on a particle of mass m , the particle remains in equilibrium. If the force vec(F)_(1) is now removed then the acceleration of the particle is :
