MHT CET 2025 Physics question
Four charges 2 μC, -3 μC, 4 μC, -4 μC and -1 μC are enclosed by the Gaussian surface of radius 2 m. Net outward flux through the Gaussian surface is (in μV-m) [ = permittivity of free space]
Answer: (A)
Solution
By Gauss's law the net flux depends only on the total enclosed charge: . Here , so in units of , i.e. the magnitude of the flux is (the negative
