Answer:
The distance between the charges is 9.5 cm
(c) is correct option
Explanation:
Given that,
Charge 
Force F = 1 N
We need to calculate the distance between the charges
Using Coulomb's formula

Where, q = charge
r = distance
F = force
Put the value into the formula




Hence, The distance between the charges is 9.5 cm
Answer:
D, using a spring scale to exert a force on the block. Measure the acceleration of the block and the applied force
Explanation:
For this you would use the net force equation acceleration=net force * mass however you will want to isolate mass so it would be acceleration/ net force to get mass. Then process of elimination comes to play.
