Explanation / Answer

part a)

magnitude of electric force = k * Q1 * Q2/d^2

magnitude of electric force = 9 *10^9 * 15 *10^-9 * 16 *10^-9/0.35^2

magnitude of electric force = 1.76 *10^-5 N

b)

as the charges are of oposite , they will attract each other

the direction of force on Q2 is towards Q1

direction of Q2 is to the left

c)

acceleration of Q2 = force/mass

acceleration of Q2 = 1.76 *10^-5/(6.5 *10^-6)

acceleration of Q2 = 2.7 m/s^2

the acceleration of Q2 is 2.7 m/s^2
