A person is standing in an elevator. In which situation he finds his weight less?

A magnet is made to oscillate with a particular frequency, passing through a coil as shown in figure. The time variation of the magnitude of e.m.f. generated across the coil during one cycle is:

Two concentric conducting thin spherical shells $A$ and $B$ having radii $r_A$ and $r_B$ ($r_B>r_A$) are charged to $Q_A$ and $-Q_B$ ($|Q_B|>|Q_A|$). The electrical field along a line (passing through the centre) is:

Dimension of electrical resistance is:

Four point $+ve$ charges of same magnitude ($Q$) are placed at four corners of a rigid square frame as shown in figure. The plane of the frame is perpendicular to $Z$ -axis. If a $-ve$ point charge is placed at a distance $z$ away from the above frame ($z\ll L$) then:
