All the Best! 1 / 10 When can a Gaussian surface be chosen arbitrarily? When charge distribution is symmetric Only when shape is spherical Only when shape is cylindrical For all shapes 2 / 10 Which parameter determines the magnitude of the electric field due to an infinite plane sheet of charge? Distance from the sheet Charge density only Permittivity only Both distance and permittivity 3 / 10 What is the nature of the electric force between two like charges? Attractive Repulsive Zero Constant 4 / 10 In classical physics, which physical quantity is quantised: Space Time Gravity Electric charge 5 / 10 When a body is earthed, what happens to its excess charge? It vanishes It gets doubled It stays on body It goes to earth 6 / 10 What is the direction of the electric field at a point due to a positive point charge? Radially inward Radially outward Circular Tangential 7 / 10 Why can a conductor be used to shield sensitive instruments from external electric fields? Because electric field inside is zero Because it absorbs all charge Because it increases field lines Because it repal charges 8 / 10 Which law can be derived using inverse-square nature of Coulomb’s law? Gauss’s Law Ohm’s Law Ampere’s Law Faraday’s Law 9 / 10 Why do sharp ends of a conductor have higher charge density? Larger surface area Smaller radius of curvature Uniform charge Large amount of charge 10 / 10 What is the electric field due to an infinite plane sheet of charge with surface charge density σ? E = 0 E = σ/ε₀ E = 2σ/ε₀ E = σ/2ε₀ Your score is 0% Restart quiz
