Syllabus context
Part of Electrostatics in JEE Main Physics.
- Electric charges: conservation of charge, Coulomb's law forces between two point charges, forces between multiple charges, superposition principle and continuous charge distribution
- Electric field: electric field due to a point charge, electric field lines, electric dipole, electric field due to a dipole, torque on a dipole in a uniform electric field
- Electric flux, Gauss's law and its applications to find field due to infinitely long uniformly charged straight wire, uniformly charged infinite plane sheet and uniformly charged thin spherical shell
- Electric potential and its calculation for a point charge, electric dipole and system of charges
- Potential difference, equipotential surfaces, electrical potential energy of a system of two point charges and of electric dipole in an electrostatic field
- Conductors and insulators, dielectrics and electric polarization
- Capacitors and capacitance, the combination of capacitors in series and parallel
- Capacitance of a parallel plate capacitor with and without dielectric medium between the plates, energy stored in a capacitor

Q2PhysicsUnit 11: Electrostatics
A material that does not allow
electricity to flow through it is called
Q3PhysicsUnit 11: Electrostatics
Assertion
When two charged metal spheres are connected by a long wire, then, the
surface charge density on each sphere is inversely proportional to the radius.
Reason
When two charged metal spheres are
connected, charge will flow from one to the other until their potentials are
equal.
Q4PhysicsUnit 11: Electrostatics
Two identical conductors of copper and
aluminium are placed in an identical electric field. The magnitude of induced charge in the aluminium will be :
Q5PhysicsUnit 11: Electrostatics
Assertion
During storms, communication may be disrupted, and electrical discharges may be seen between sharp points on signalling equipment that is
inadequately earthed.
Reason
Atmospheric electricity often has an effect on electrical communications.
Q6PhysicsUnit 11: Electrostatics
If a charge is placed on a conductor having a pointed end, then
Q7PhysicsUnit 11: Electrostatics
A positive charge and a negative charge are held in place and initially form a
dipole. Then a uncharged conducting bar is placed in between them.
How is the force between the charges
affected?
Q8PhysicsUnit 11: Electrostatics
A positively charged rod is brought near an uncharged conductor. If the rod is then suddenly withdrawn, the charge left on the conductor will be :
