Empenneuse Cartel Mode D' Emploi, Two metal spheres A and B are suspended from two silk threads and a positively charged glass rod is held near A, as shown in diagram. Draw a free-body diagram for each ball: Suppose the charge on the second ball is reduced slightly, so that it is less than that on the first ball. Find the tension in the bottom thread. Then calculate the distance x in the equilibrium state. Assuming theta is very small find an expression for x. Note that Newton's third law (every force exerted creates an equal and opposite force) applies as usualthe force on is equal in magnitude and opposite in direction to the force it exerts on . Two small equally charged spheres, each of mass m, are suspended from the same point by silk threads of length l. The distance between the spheres x << l. Find the rate dq/dt with which the charge leaks off each sphere if their approach velocity varies as v = a/\(\sqrt V\) bar x, where a is a constant. Both balls have the same net charge. Charging by induction using a ground connection. You are using an out of date browser. Then rub the glass rod on the silk to charge the rod positively (hence to charge piece of silk negatively). Thus, we can say that repulsion is the surest test of electrification. An equal number of electrons is placed on two metal spheres 3.0 cm apart in air.
