Class XII Electric charges are of 2 types 5 types 3 types 4 types For charges q1and q2q1and q2 separated by a distance R the magnitude of the electrostatic force is given by F = . q1q2 4πϵ0R2 F = q1 4πϵ0R2 F = q1q2 4πϵ0R F = q1q2 4πϵ0R3 An electric dipole in an electric field experiences a torque τ⃗ equal to the scalar product of E⃗ E→ and p⃗ equal to the scalar product of p⃗ p→ and E⃗ equal to the vector product of E⃗ E→ and p⃗ equal to the vector product of p⃗ p→ and E⃗ In charging by Induction a metallic object is charged by rubbing it with silk a metallic object by touching touching with a charged object a metallic object is charged by rubbing it with fur a metallic object is charged by bringing a charged object near it The unit of charge is volt ampere ohm coulomb Do you really want to submit this quiz?
