1. What are the major differences between investor-owned and not for-profit corporations? 2. What…

1. A negative point charge Q is placed at distance of r from the surface of an uncharged conducting sphere of radius R. The net charge on the sphere will be (a) positive (b) negative (c) positive if r < r="" and="" negative="" if="" r="" R (d) zero 2. A capacitor of capacitance C1 is charged to the voltage V of a battery as shown in Fig. 11.80. The fraction of its stored energy dissipated after the switch S is disconnected from 1 and connected to 2 is 3. Three non-conducting spheres 1, 2 and 3 have radii R, 2R and 3R respectively. Equal charge Q is uniformly distributed in each sphere. If E1, E2 and E3 are the magnitudes of electric fields at point P at a distance 2R from the centre of spheres 1, 2 and 3 respectively as shown in Fig. 11.81, then
