A non-conducting sphere of radius R = 0.1 no, mass M. = 10 kg and uniform mass density carries a surface charge density or = oncos, with on = 10 microCoulomb. (a) Find the dipole moment p0 of the sphere. [b]: Assume that at t = 0 the sphere receives an angular impulse and starts rotating about the x-axis with angular velocity {on = 100015. Calculate the power radiated by the sphere when it rotates with angular frequency to. {c} Estimate the time it takes for the rotation rate of the sphere to decrease by a factor of 2
