Class XII

Electric field at a point is defined as
  1. electric force experienced by a charge at that point
  2. electric force per unit charge experienced by a unit charge at that point
  3. electric force experienced by two charges at that point
  4. electric force per unit charge experienced by a unit charge at that point
electrostatic force is
  1. force exerted by one charge on another when the two are accelerating in a given frame of reference
  2. force exerted by one charge on another when the two are moving in a given frame of reference
  3. force exerted by an electron on a neutron
  4. force exerted by one charge on another when the two are at rest in a given frame of reference
A conducting sphere of radius 5 cm is charged to 15 μμ C. Another uncharged sphere of radius 10 cm is allowed to touch it for enough time. After the two are separated, the surface density of charge on the two spheres will be in the ratio
  1. 1:2
  2. 2:1
  3. 1:1
  4. 3:1
A Gaussian sphere encloses an electric dipole within it. Total flux across the sphere is
  1. double that due to single charge
  2. dependent on position of the charge
  3. half that due to a single charge
  4. Zero
Conductors are materials
  1. that allow only random movement of electrons
  2. that allow movement of protons
  3. that allow movement of electrons
  4. that allow movement of neutrons
