Question

A point charge causes an electric flux of -6 x 10 3 Nm2C -1 to pass through a spherical Gaussian surface is doubled, how much flux will pass through the surface? What is the value of Charge

Answer 1

Answer:

Electric flux = -12 x $10^{3}$ Nm2C -1

Charge = - 1.35 x $10^{15}$

Explanation:

∅ = E.ds

Electric flux when doubled

∅1 = E x 2 x ds

     = 2 x ∅

     = 2 x -6 x $10^{3}$ = - 12 x $10^{3}$ Nm2C -1

∅1 = $\frac{1}{Eo}$ x Q

Q  = - 12 x $10^{3}$  / 8.85 x $10^{-12}$

    = - 1.35 x $10^{15}$ C
