Q1. A 362 g object is attached to a spring and executes simple harmonic motion with the period of 0.200 s. If the total energy of the system is 6.71 J.
Find out the maximum speed of the object.
Q2. Two point charges, Q1= -23 microC and Q2= 52 microC, are separated by the distance of 12 cm. The electric field at point P is zero (which is to the left of Q1). How far from Q1 is P?
