Q1 CHARGE AT INNER SHELL

Q2 CHARGE AT OUTER SHELL

FIELD OUT SIDE IS 0 AS TOTAL CHARGE ENCLOSED IS 0

Q1 >Q2

SO NET CHARGE ENCLOSE WILL BE +ve

Q1 <Q2
THIS MEANS BOTH CHARGES R -ve

SO FIELD POINTS INWARD

q1 is +ve only and q2 -ve so when said about comparison of charge it means magnitude i thnk..

Yeah Abhishek is right. I think Tanay's 3rd diagram is wrong.... There is still pos. charge on the inside, so field lines still go radially outwards dont they?

in 3rd if we take magnitude only its wrong bt if v take signs also its corrct

The NET CHARGE is negative, but E field always points from positive to negative!
