Identify the option that represents the correct configuration of electric field lines due to a combination of one positive and one negative charge.
Important Questions on Electrostatics
A charge is placed at in the cavity in a spherical uncharged conductor. Point is outside the conductor. If the charge is displaced from towards still remaining within the cavity,
Assertion: No two electric lines of force can intersect each other.
Reason: Tangent at any point of electric line of force gives the direction of electric field.
The figure shows the electric lines of force emerging from a charged body. If the electric fields at and are and respectively and if the distance between and is , then
A long cylindrical shell carries positive surface charge in the upper half and negative surface charge in the lower half. The electric field lines around the cylinder will look like figure given in: (figures are schematic and not drawn to scale)
