"Gauss's law is true for any closed surface, no matter what its shape or size" say the following statements are true or false.
a. Gauss's law implies that the total electric flux through a closed surface is zero if no charge is enclosed by the surface.
b. This law is useful for the calculation of electrostatic field when the system doesn't possess any symmetry.
c. In a uniform electric field, we know that the dipole experiences no net force, but experiences a torque having a relation with P and E is given by ............ where the parameters P and E have their usual meaning.
