State whether the following statement are true of false giving reason in brif :
(a) The dimension of `(h//e)` is the same as that of magnetic flux `phi`.
(b) The dimensions of electric and magnetic flux are same.
(c ) A coil or a metal wire is kept stationary in a non-uniform magnetic field. An e.m.f. is induced in the coil.
(d) An e.m.f. can be induced between the two ends of a straingth copper wire when it is moved through a magnetic field.

Text Solution

Verified by Experts

(a) True.
`(h)/(e) = ("joule - sec")/("coulomb") = ("joule")/("ampere")`
= magnetic flux
(b) False, for reason, see text.
(c ) False, As magnetic flux does not change with time.
(d) True, as `e = B upsilon l sin theta`.
