Express your answer using two significant figures Constants Two 3.0 kg masses are 4.0 m apart on a frictionless table Each has 1 0 Jd charge You may wane to review (Pees 542-644 Part B what is tho inhal accelerason af each mass if they, released and anowed move? Express your answer using two significant figures m/s

Explanation / Answer

part a)

magnitude of electric force = k * q^2/r^2

magnitude of electric force = 9 *10^9 * (1 *10^-6)^2/4^2

magnitude of electric force = 5.63 *10^-4 N

the magnitude of electric force is 5.6 *10-4 N

part b)

initial acceleration = electric force/mass

initial acceleration = 5.63 *10^-4/3

initial acceleration = 1.9 *10-4 m/s^2
