Answer:
q = 5 coulombs.
Explanation:
Given :
Potential of battery , V = 9 V.
Work done in transferring charge from negative terminal to the positive terminal , W = 45 J.
We know, Work done by charge is product of its charge by its potential.
[tex]W=q\times V[/tex]
Therefore, [tex]q=\dfrac{W}{V}[/tex]
Putting values of W and V in above equation.
We get , [tex]q=\dfrac{45}{9}=5\ coulombs.[/tex]
Hence, this is the required solution.
