Field at origin = 0 (as it is conductor) = field due to induced charges + field due to Q
=> field due to induced charges = -(field due to Q) = Q4piεk2 (towards -ve x-axis_
A point charge Q is placed at x=k on the x-axis, k>1.
There's a conducting sphere at the origin, of radius 1 unit.
Find the field at the origin due to induced charges.
Field at origin = 0 (as it is conductor) = field due to induced charges + field due to Q
=> field due to induced charges = -(field due to Q) = Q4piεk2 (towards -ve x-axis_
Thanx, I was thinking field due to induced charge would be 0 .........and what-all non-sense!
