A particle (m = 50 g, q = 5.0 mC) is released from rest when it is 50 cm from a second particle (Q = -20 mC). Determine the magnitude of the initial acceleration of the 50-g particle.
You will use the coulomb force equation and equate it with newton's force law to find the particle's acceleration: [tex]ma = \frac{1}{4 \pi \epsilon _0} \frac{qQ}{r^2} [/tex]
