Q1. A 220 g block is attached to a horizontal spring and executes simple harmonic motion with a period of 0.150 s. If the total energy of the system is 3.50 J.

Q2. A spherical cavity of radius 4.50 cm is at the center of a metal sphere of radius 18.0cm. A point charge Q = 5.50 mC rests at the very center of the cavity, whereas the metal conductor carries no net charge. Find out the electric field at a point.
