Define electric flux. Write its S.I.unit. A charge q is enclosed by a spherical surface of radius R. If the radius is reduced to half, how would the electric flux through the surface change? |
Answer» Electric flux linked with a surface is the number of electric lines of force cutting through the surface normally. It’s SI unit is Nm2C –1 or Vm on decreasing the radius of spherical surface to half there will be no effect on the electric flux. |
