The motion of copper plate is damped when it is allowed to oscillate between the two poles of a magnet.If slots are cut in the plate,how will the damping be affected?

Two holes are made in copper plate. The plate is heated. The distance between the holes

When potential difference of 9V is applied between the two plates, electron accelerate between the plates with velocity

A metal wire of linear mass density of 9.8g//m is stretched with a tension of 10 kg-wt between two rigid support 1meter apart. The wire passes at its middle point between the poles of a permanent magnet, and it vibrates in resonance when carrying an alternating current of frequency n . the frequency n of the alternating source is

A light pointer fixed to one prong of a tuning fork touches a vertical plate. The fork is set vibrating and the plate is allowed to fall freely. If eight oscillations are counted when the plate falls through 10 cm, the frequency of the tuning fork is

Assertion : When there is a thin layer of water between two glass plates , there is a strong attraction between them . Reason : The pressure between the plate becomes less than atmospheric pressure because pressure inside a bubble or drop is greater than outside pressure.

In a parallel plate capacitor with air between the plates, each plate has an area of 6 xx 10^-3 m^2 and the separation between the plates is 2 mm. How would charge on the plates be affected if a 2 mm thick mica sheet of k = 6 is inserted between the plates while the voltage supply remains connected ?

Why are the oscillations of a copper disc in a magnetic field highly damped?

In a parallel plate capacitor with air between the plates, each plate has an area of 6 xx 10^-3m^2 and the separation between the plate is 4mm:- How would the charge on the plates be affected if a 2mm thick mica sheet of k = 6 is inserted between the plates while the voltage supply remains connected?
