50. The electric field in a region is given by £ - 41 +10 ) N/C. The flux of this field through a square of
10 cm on a side whose plane is parallel to the XZ plane
(A) 4 Vm
(B) 10 Vm
(C) 1 Vm
(D) 0.4 Vm​

Answer 1

Answer:

Number of lines of electric force crossing is equal to flux (ϕ)

We know ϕ=∫E.da

→ By keeping area constant and doubling E, ϕ will also get doubled.

∴ Number of lines get doubled =80
