1,200 hours multiply by 60W will give you 72000kW. Convert it to kW. That will give you 0072.00kW.
Answer:
933.804423995 m/s²
Explanation:
= Charge on particle 1 = 67 µC
= Charge on particle 2 = -25 µC
r = Distance between the particles = 47 cm
k = Coulomb constant = 
m = Mass of particle = 73 g
Electric force is given by

The magnitude of force is 68.1677229516 N
Acceleration is given by

The acceleration is 933.804423995 m/s²
