Electrostatics (Test 2) Electrostatics (Test 2) 1 / 10A charge q is placed at the center of a cube. The flux through one face of the cube is: q/ε₀ q/(6ε₀) q/(4πε₀) Zero 2 / 10The energy stored in a capacitor is given by: CV² ½CV² V/C C/V 3 / 10The capacitance of a parallel plate capacitor increases if: Distance between plates increases Area of plates decreases Dielectric constant increases Vacuum is used 4 / 10The force between two charges in vacuum is F. If a dielectric of constant K is introduced, the force becomes KF F/K F/K² √F/K 5 / 10The electric potential due to a dipole at a point on its axial line is proportional to: 1/r 1/r² 1/r³ r 6 / 10A capacitor is charged and then disconnected from the battery. If the plates are pulled apart, the potential difference Increases Decreases Remains same Becomes zero 7 / 10The unit of electric field is: V V/m C N 8 / 10The electric field due to a uniformly charged spherical shell inside the shell is: Maximum Zero Infinite Constant 9 / 10The potential energy of a system of two charges q₁ and q₂ separated by distance r is: q₁q₂/r q₁q₂/(4πε₀r) q₁q₂r q₁ + q₂ 10 / 10The electric field at the surface of a conductor is: Perpendicular to surface Parallel to surface Zero Tangential Your score isThe average score is 0% 0% Restart quiz
