The pan attached to a spring balance has a mass of 1 kg. A weight of kg when placed on the pan stretches the spring by 10 cm. What is the frequency with which the empty pan will oscillate ?

A pan of 2 kg is attached to a spring balance. When a weight of 3 kg is placed on the pan. The spring is stretched by 12 cm. Calculate the frequency with which the empty pan will oscillate.

A weight of 3 kg is placed on the pan of mass 1kg of a spring balance. IF the weight stretches the spring by 12 cm, find the frequency with which the empty pan oscillates.

A mass of 1kg is hanged through a spring. The spring is stretched through 1cm. What is the energy stared in spring?

Two 2 kg weight are attached to spring balance as shown in figure-2.122. What is the reading of the scale ?

A false balance has equal arms. An object weights W_1 when placed in one pan and W_2 when placed in the other pan. The true weight W of the object is.

When a 1.0kg mass hangs attached to a spring of length 50 cm, the spring stretches by 2 cm. The mass is pulled down until the length of the spring becomes 60 cm. What is the amount of elastic energy stored in the spring in this condition. if g = 10 m//s^(2).

A false balance has equal arms. An object weigh X when placed in one pan and Y when placed in other pan, then the weight W of the object is equal to

A body of mass m falls from a height h onto the pan of a spring balance. The masses of the pan and spring are negligible. The force constant of the spring is k. The body sticks to the pan and oscillates simple harmonically. The amplitude of oscillation is

A body of mass m falls from a height h on to the pan of a spring balance. The masses of the pan and spring are negligible. The spring constant of the spring is k. Having stuck to the pan the body starts performing harmonic oscillations in the vertical direction. Find the amplitude and energy of oscillation.
