Four pendulums A, B, C and D are suspended from the same elastic support as shown in figure. A and Care of the same length, while B is smaller than A and D is larger than A.If A is given a transverse displacement, then

Four pendulums A, B, C and D are suspended from the same elastic support as shown in figure. A and Care of the same length, while B is smaller than A and D is larger than A.If A is given a transverse displacement, then(a) D will vibrate with maximum amplitude(b) C will vibrate with maximum amplitude(c) B will vibrate with maximum amplitude(d) all the four will oscillate with equal amplitude

A suspended simple pendulum of length ℓ is making an angle θ with the vertical. On releasing, its velocity at lowest point will be :-

A child swings sitting and standinginside swing as shown in figure, thenperiod of oscillations has the relation(a) (𝑇)𝑆𝑖𝑡𝑡𝑖𝑛𝑔 = (𝑇)𝑆𝑡𝑎𝑛𝑑𝑖𝑛𝑔(b) (𝑇)𝑆𝑖𝑡𝑡𝑖𝑛𝑔 > (𝑇)𝑆𝑡𝑎𝑛𝑑𝑖𝑛𝑔(c) (𝑇)𝑆𝑖𝑡𝑡𝑖𝑛𝑔 < (𝑇)𝑆𝑡𝑎𝑛𝑑𝑖𝑛𝑔(d) 2(𝑇)𝑆𝑖𝑡𝑡𝑖𝑛𝑔 = (𝑇)𝑆𝑡𝑎𝑛𝑑𝑖𝑛𝑔

A pendulum consisting of a small sphere of mass m, suspended by an inextensible and massless string of length l, is made to swing in a vertical plane. If the breaking strength of the string is 2 mg then the maximum angular amplitude of the disc placement from the vertical can be

Question #1You put the same amount of weight at the end of these two pendulums. If you let go of the two pendulums at the same time, which will swing faster?A B No difference
