Statement I : For practical purpose, the potential of the earth is used as a reference, and is assumed to be the zero of potential in electrical circuits. Statement II : The electrical potential ofa sphere of radius R, with charge Q uniformly distributed on its surface is given by Q/(4 pi epsilon_(0)R) .

This question has statement and statement II of the four choices given after the statements choose the one that best describes the two statements Statement-I:the angular velocity of a geostationary satellite w.r.t any point on the earth is zero Statement-II:the geostationary satellites is used for weather forecasting

This question has Statement -1 and Statement 2. Of the four choices given after the statements, choose the one that best describes the two statements . An insulating solid sphere of radius R has a uniform positive charge density p. As a result of this uniform charge distribution, there is a finite value of electric potential at the centre of the sphere, at the surface of the sphere and also at a point out side the sphere. The electric potential at infinity is zero. Statement -1: When a charge q is taken from the centre to the surface of the sphere, its potential energy changes by (qp)/(3epsilon _0) Statement - 2 : The electric field at a distance (rltR) from the centre of the sphere is (pr)/(3epsilon _0)
