Answer: C. 1.64 x 10-3 m/s2
Answer:
1995 and 2000 , 4 trillions
Explanation:
Answer: The initial force is reduced a factor 1/4 when the separation between charge is doubled
Explanation: As it well known the electric force between two charges is given by:
Finitial=k*q1*q2/d^2 where d is the distance between charges and k is a constant
if the distance is doubled this means 2*dinitial thus the new force is equal to F initial* 1/4
450 J / 3 s = 150 J/s = 150 watts.
