Positive Two identical charged spheres suspended from a common point by two massless strings of lengths l, are initially at a distance d (dl) apart because of their mutual repulsion. A rigid electric dipole is free to move in the electric field represented in the figure. E) There is no excess or deficiency of electrons. The potential energy of the spring is at a minimum at x = 0. At which of the following times is the upward velocity of the object the greatest? B To stretch a certain nonlinear spring by an amount x requires a force F given by F = 40x -6x2, where F is in newtons and x is in meters. A closed cylindrical shell is placed close to an object with a charge of Q, as shown. The two halves are then rejoined with insulation at the junctions J, as shown above. C The interaction energy between two experiment charge e hard spheres is therefore (Fig. B Which one of the following table entries is a possible combination of the signs of the net charges on these three objects? E When the spacecraft is at position P shown, a short burst of the ship's engines results in a small increase in its speed. Angular Momentum: Increases 3) the polythene strip is removed. A block of mass 1.2 kilograms is suspended from the pair of springs, as shown above. B Epub . D B Q. (b) Next the spheres are moved away from each other. 2T D In your explanation, include clear diagrams. When the block is set into oscillation with amplitude A, it passes through its equilibrium point with a speed v. 2. D Identify the main term in the following diagnoses. The radius of the sheet is R. Point O is at the center of the sheet. Classify each of the following substances as a nonelectrolyte, weak electrolyte, or strong electrolyte in water: A simple pendulum of length L has a period T.
