Question
The figure shows two situations in which Gaussian cube sits in an electric field. The arrows and values indicate the directions and what is the net charge (in the two situations) inside the cube?
Options
A.(1) nagative (2) positive
B.(1) nagative (2) zero
C.(1) positive (2) positive
D.-
Solution
The field lines in 1are :
(6 + 7)out - (2 + 7 + 15 + 8) in = 19 (in)
It represents negative charge.
The field lines in 2are :
(9 + 5 + 6) out - (7 + 3 + 2) in = 8 (out)
It represent positive charge.
(6 + 7)out - (2 + 7 + 15 + 8) in = 19 (in)
It represents negative charge.
The field lines in 2are :
(9 + 5 + 6) out - (7 + 3 + 2) in = 8 (out)
It represent positive charge.
