Homework Statement
Magnetic field in the cylindrical region with its axis passing through O varies at a constant rate x. A triangular imaginary loop ABC, with AB = BC, is lying in this region as shown in figure. The work done to move unit positive charge from A to B along side AB is:
(a) r2 x
(b) [tex]\pi[/tex] r2 x
(c) r2/2 x
(d) 3r2/4 x
Homework Equations
emf induced in a circular loop of radius a due to time varying magnetic field = [tex]\pi[/tex] a2 x
work done in moving a charge q = qV
The Attempt at a Solution
Honestly, I have no clue how to go about it. Electric field is non-conservative, so we can't simply find the potential difference. When I tried to integrate E.dl , I could not find the angle between electric field and displacement. I feel pretty sure that we need to integrate, but how? A hint would be sufficient.
thanks in advance.
