Potential Energy

Assuming potential energy 'U' at ground level to be zero. All objects are made up of same material :- {:(U_(P) = "Potential energy of solid sphere",U_(Q) = "Potential energy of solid cube",),(U_(R ) = "Potential energy of solid cone",U_(S) = "Potential energy of solid cylinder",):}

In a simple harmonic motion (i) the maximum potential energy equal the maximum kinetic energy (ii) the minimum potential energy equals the minimum kinetic energy (iii) the minimum potential energy equals the maximum kinetic energy (iv) the maximum potential energy equals the minimum kinetic energy

A particle is performing linear S.H.M. at a point A, on the path, its potential energy is three times kinetic energy. At another point B on the same path, its kinetic energy is 3 times the potential energy. The ratio of the potential energy at A to its potential energy at B is
