A pendulum consists of a bob of mass m = 0.1 kg and a massless inextensible string of length L = 1.0 m. It is suspended from a fixed point at height H = 0.9 m above a frictionless horizontal floor. Initially, the bob of the pendulum is lyin...

Two concentric circular loops, one of radius R and the other of radius 2R, lie in the xy-plane with the origin as their common center, as shown in the figure. The smaller loop carries current I1 in the anti-clockwise direction and the large...

When the dipole m is placed at a distance r from the center of the loop (as shown in the figure), the current induced in the loop will be proportional to

The work done in bringing the dipole from infinity to a distance r from the center of the loop by the given process is proportional to

A physical quantity \(\overrightarrow S\) is defined as \(\overrightarrow S = (\overrightarrow E \times \overrightarrow B )/{\mu _0}\), where \(\overrightarrow E\) is electric field, \(\overrightarrow B\) is magnetic field and \(\mu\)0...

A source, approaching with speed u towards the open end of a stationary pipe of length L, is emitting a sound of frequency fs. The farther end of the pipe is closed. The speed of sound in air is v and f0 is the fundamental frequency of the ...
