Answer
(b)
2 +A
02
Z = R /3
Electric field at the centre O due to loop 1 is
given by
= 0 (As Z =
0)
Electric field at a point outside the loop 2 on the
axis passing normally through O, of loop 2 is
AR
2€0' (R2+Z² 3/2
Since Z =
R/3
AR
R/3
2€0 (R²+3R? )³/2
towards right (As A is positive)
16:0R
So, net electric field at the centre of loop 1
E 1+ E 2
= 0 +
16€0 R
16:0R
