A pointcharge + mu c is a distance 5 cm directly above the centre of a square of side 10 cm aswhat is the magnitudeof the electricflux throughthe square |
Answer» Solution :Situation given in the statement is equivalent to following situation.  Here given point charge `q= 10 muC`can be considered to be at the centroid of a cube of side length 10 cm. This POSITION of charge is SYMMETRIC to all the six identical faces of a cube. Hence, total ELECTRIC FLUX `phi_(t)`emanating from charge q is shared equally by these six faces. Hence, electric flux passing through one face (bottom face given in the statement) will be, `PHI = 1/6 phi_(t)` `=1/6 (q/epsilon_(0))` `=(10 xx 10^(-6))/(6v xx 8.85 xx 10^(-12))` `therefore phi = 1.883 xx 10^(5) Nm^(2)//C` |
