Flux (in S.I. units) coming out and eantering a closed surface is shown in the figure. Find charge enclosed by the closed surface.

Text Solution

Verified by Experts

Net flux though the closed surface `=+ 20+30+10-15=45 N.m^(2)//c`
From Gauss's theorem : `phi_("net")=q_("in")/epsi_(0)`
or `45=q_("in")/epsi_(0)" ":. " "q_("in")=(45) epsi_(0)`
