E B Which of the following equations results from a correct application of Gauss's law for this situation? At x = 0, its velocity is zero. If density of the material of the sphere is 1.6 g cm -3 , the dielectric constant of the liquid is : Let E be the electric field magnitude at a distance r from the center of the spheres. LBb? 0.25 s, Assuming air resistance is negligible, how does a diver doing flips off a diving board change rotational speed in midair? As a result the charges approach each other with a velocity . 3) the polythene strip is removed. Objects A and B attract one another. D The speed of the center of mass of the stick-arrow system after the arrow strikes is given by which of the following expressions? Two identical charged spheres suspended from a common point by two massless strings of length L.In ,The charge begins to leak from both the sphere at a constant rate. Does sphere C end up with an excess or a deficiency of electrons and how many electrons is it? A pupil wants to charge a metal ball by induction, using a strip of polythene. Two fixed charges A and B of 5muC each are seperated by a distance of 6m. 0000012268 00000 n 14. A Two identical pith balls are charged by rubbing against each other. Three particles each with charge +Q are placed on three corners of a square, as shown. E/2 Answer 1. Article Google Scholar As a result, the spheres approach each other with a velocity v . E B Two identical charged spheres suspended from a common point by two massless strings of lengths l, are initially at a distance d (d << l) apart because of their mutual repulsion. A B C D E Figure 14.70 D Two small identical small spheres with mass m are hung from insulating threads of length L, as shown in the gure. Spheres B and C are then touched and separated. C Then: A 1 > 2 B 1 < 2 C 1= 2 D the tension in A is greater than that in B C The strings make an angle of 30 o with each other. I and II only C In which configuration is the electric field at P equal to zero? B According to Coulombs law, these two like 0000004648 00000 n A block of mass of M 2 is attached to the free end of the rope. ve/2 Quantities that are conserved for the student-platform system as the student jumps include which of the following? As a result, the spheres approach each other with a velocity v. Then v varies as a function of the distance x between the spheres as, Two positively charged spheres of masses m1 and m2 , are suspended from a common point at the ceiling by identical insulating massless strings of length l.
