The force between two charges is 120 N. if the distance between the charges is doubled, the force will be 30 N.
2.The electric field intensity at a point situated 4 meters from a point charge is 200 N/C. If the distance is reduced to 2 meters, the field intensity will be
17.Two metal plates distance ?d? apart from a capacitor of value C farads. Another metal plate of thickness d/2 and of the same areas is inserted in between these two plates, capacitance of this three plate capacitor will be
Electric field inside a hollow metallic charged sphere is Zero.
19.Two plates of parallel plate capacitor after being charges from a constant voltage source is separated apart by means of insulated handles, then the
Varying voltage produces the charging and discharging currents
Explanation:
If AC voltage is applied to capacitive circuit, the alternating current can be flow in the circuit because Varying voltage produces the charging and discharging currents.
