To solve this problem we will apply the concepts related to Coulomb's law for which the Electrostatic Force is defined as,

Here,
k = Coulomb's constant
= Charge at each object
r = Distance between them
As the distance is doubled so,





Therefore the factor is 1/4
High digital and high are the answers.
hope this helps
Answer:
Ws=8.75 Watts
Explanation:
As per fig. of prob 02.061, it is clear that R5 and R4 are in parallel, its equivalent Resistance will be:



Now, this equivalent Req45 is in series with R3, therefore:

This Req345 is in parallel with R2, i.e

Now this gets in series with R1:

Now, the power delivered Ws is:
