Question 24 5 pts The following questions are all statements. You need to decide True (T) or False (F) for each ad then select the appropriate from the multiple choice answer below (i) A ball of charge 100 e lies at the center of hollow sphere metal shell that has a net charge of -150 e. The charge on the outer surface of the shell should be +250e (note 1e = 1.6 x10-1⁹ C) T F (ii) A dielectric with dielectric constant k=4 is inserted between the plates of a capacitor. The electric field E, Potential difference V and energy density n all decrease once the dielectric is inserted T F (iii) If the resistance in A is suddenly decreased, the induced current in B is CCW, T F non B (iv) EM wave are longitudinal waves and travel in the direction of Poyintng vector S and have same speed in air and vacuum T F (v) A current loop has its magnetic moment anti- parallel to the B field produces maximum torque in loop TF (i) (ii) (iii) (iv) (v) A.
