A uniform rod of length L and mass M is pivoted at the centre. Its two ends are attached to two springs of equal spring constants \(k\). The springs are fixed to rigid supports as shown in the figure, and the rod is free to oscillate in the...

A student performed the experiment to measure the speed of sound in air using resonance air-column method. Two resonances in the air-column were obtained by lowering the water level. The resonance with the shorter air-column is the first re...

Column I shows four situations of standard Young's double slit arrangement with the screen placed far away from the slits S\(_1\) and S\(_2\). In each of these cases, S\(_1\)P\(_0\) = S\(_2\)P\(_0\), S\(_1\)P\(_1\) \(-\) S\(_2\)P\(_1\) = $$...

Under the influence of the Coulomb field of charge +Q, a charge \(-\)q is moving around it in an elliptical orbit. Find out the correct statement(s):

A 20 cm long string, having a mass of 1.0 g, is fixed at both the ends. The tension in the string is 0.5 N. The string is set into vibrations using an external vibrator of frequency 100 Hz. find the separation (in cm) between the successive...

A light inextensible string that goes over a smooth fixed pulley as shown in the figure connects two blocks of masses 0.36 kg and 0.72 kg. Taking g = 10 m/s2, find the work done (in joules) by the string on the block of mass 0.36 kg during ...

Three objects A, B and C are kept in a straight line on a frictionless horizontal surface. These have masses m, 2m and m, respectively. The object A moves towards B with a speed 9 m/s and makes an elastic collision with it. Thereafter, B ma...
