In the space shown a non-uniform magnetic field `vec(B) = B_(0)(1+x)(-hat(k))` tesla is present. A closed loop of small resistance, placed in the `x y` plane is given velocity `V_(0)`. The force due to magnetic field on the loop is

A

(a) zero

B

(b) along + x direction

C

( c) along - x direction

D

(d) along + y direction

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) Use Lenz's law. Induced emf of the current opposes the change in flux through it.

There exists a uniform magnetic field vec(B) = +B_(0) hat(k) " for " x gt 0 and vec(B) = 0 for all x lt 0 . A charged particle placed at (0, -a,0) is given an initial velocity vec(v) = v_(0) hat(i) . What is the magnitude and nature of charge on the particle such that it crosses through the origin ? Strategy: When the charge is projected perpendicular to a uniform magnetic field, it follows a circular path. In this case, the force acting on it will be directed either towards +y-axis. or y-axis. It is given that it crosses point O. Thus, the force at (0, -a, 0) must be towards y-axis
