Question

The ratio of force between two charges at 2 m from each other​

Answer 1

Explanation:

hope it helps u this is the answer

Answer 2

Answer:

Explanation:

Charge is conserved so

Q1+Q2=Q3+Q4                                  

Q1 and Q2 are initial charges and Q3 and Q4 are charges after connecting them

Q3=Q4=Q ( they are identical )

So Q=  

2

10+20

​  

 

Q=15C

Ratio of forces =K(10)(20):K(15)(15)
