Question

1) Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of magnitude F due to the other. With time, charge gradually diminishes on both spheres by leaking off. When each of the spheres has lost half its initial charge, what will be the magnitude of the electrostatic force on each one? A) 1/16 F B) 1/8 F Coulomos coulombs Law C) 1/4 F D) 1/2 F E) 1/2 F 2) Two point charges, Q1 and Q2, are separated by a distance R. If the magnitudes of both charges are doubled and their separation is also doubled, what happens to the electrical force that each charge exerts on the other one? A) It increases by a factor of 2. B) It increases by a factor of 2. C) It is reduced by a factor of V2. D) It increases by a factor of 4. E) It remains the same. 3) Two point charges, Q1 and Q2, are separated by a distance R. If the magnitudes of both charges are halved and their separation is also halved, what happens to the electrical force that each charge exerts on the other one? Q,02 12-4TEO (212 A) It increases by a factor of 16. - B) It increases by a factor of 8. C 4TTEO R2² C) It increases by a factor of 2. foctor of 4. Eq=Fi

Answer 1
