Time period of a block when suspended from the upper plate of a parallel plate capactor by a spring of stiffness `k` is when block ids unchanged If a change `g` is given to the block then new time period of oscilation will be

A block of mass ma is suspended vertically with a spring of spring constant k. The block is made to oscillate in a gravitation field. Its time period is fould to be T. Now the space between the plates is made gravity free, and an electric field E is produced in the downward direction. Now the block is given a charge q. the new time period of oscillation is

A block of mass m is suspended vertically with a spring of spring constant k. The block is made to oscillate in a gravitation field. Its time period is fould to be T. Now the space between the plates is made gravity free, and an electric field E is produced in the downward direction. Now the block is given a charge q. the new time period of oscillation is

A system is shown in the figure. The force The time period for small oscilations of the two blocks will be

T_(1),T_(2) are time periods of oscillation of a block when individually suspended to springs of force constants K_(1),K_(2) respectively. If same block is suspended to series combination of same two springs, then it time period of oscillation.

In a spring block system if length of the spring is reduced by 1% , then time period

A system is shown in the figure. The force The time period for small oscillations of the two blocks will be

The period of oscillation of a mass M suspended from a spring of spring constant K is T. the time period of oscillation of combined blocks is
