Answer 1

Answer:

The answer to this question is = 1 N

Explanation:

Given:

r = x

F = 16 N

F = k*q1*q2/r²

Here the F1 is the force when distance = x

F1 = k*q1*q2/x². (1)

Here F2 is the force when dictance = 4x

F2 = k*q1*q2/(4x)²

F2 = k*q1*q2/16x²

F2 = 1/16 *[ k*q1*q2/x²]. (2)

Substitute the value of (1) into (2)

We get

F2 = 1/16 * F1

F2 = F1 / 16

Substitute the value of F1 = 16 N

F2 = 16 N / 16

F2 = 1 N

I HOPE IT WILL HELP YOU.

Answer 2

Answer:

4N is the answer

Explanation:

as we know F is inversely proportional to distance

when distance is X force is 16N

when distance become 4x force become F/4

=16/4

=4N
