(b) cylindrically symmetric
(c) Planar Symmetric
(d) none of these
(Note:- This question have one or more than one correct choice(s) out of the four given choices. Any number of options may be correct.)
Explain compressibility.which type of material has higher compressibility?
A closed circular coil having a diameter of 50 cm made of 200 turns of wire with a total resistance of 10 Ω is placed with its plane at right angles to a magnetic field of strength of 10-2 T. Calculate the quantity of electric charge passing through it when the coil is turned through 1800 about an axis in its plane.
