Assertion : If three capacitor of capacitance are connected in parallel then their equivalent capacitance
Assertion : Electrons move away from a low potential to a high potential region.
Reason : Because electrons have negative charges
Assertion : If the distance between parallel plates of a capacitor is halved and the dielectric constant is made three times, then the capacitor becomes 6 times.
Reason: The capacity of the capacitor does not depend upon the charge.
Assertion : A parallel plate capacitor is connected across the battery through a key. A dielectric slab of constant K is introduced between the plates. The energy which is stored becomes K times.
Reason : The surface density of charge on the plate remains constant or unchanged.
Assertion : Work done in moving a charge between any two points in a uniform electric field is independent of the followed by a charge, between these points.
Reason : Electrostatic forces are conservative in nature.
Assertion : Electric field is always directed perpendicular to an equipotential surface.
Reason : Equipotential surface is a surface on which each point potential is same.
Asserion : Electric lines of force never cross each other.
Reason : Electric field at a point superimpose to give one resultant electric field.
Assertion : The Coulomb force is the dominating force in the universe.
Reason : The coulomb is weaker than the gravitational force.
Assertion : Of a proton and an electron are place in the same uniform electric field. They experience different accelerations.
Reason : Electric force on a test charge is independent of its mass.
