Four charges are at the corners of a square
centered at the origin as follows:
7 q at (?4 a,+3 a) ,
9 q at (+4 a,+3 a) ,
?5 q at (+4 a,?3 a) , and
9 q at (?4 a,?3 a) .
A fifth charge 9 q with mass m is placed at
the origin and released from rest
Please make clear your requirement in your question. You are provided some information but you got to mentioned your requirment.
Suppose if you want to find the value of force on fifth charge due to four charges then you will sum up the value of four forces at origin.
Same summation procedure will be done in case of finding electric field.
You must choose the co ordinate axis and resolve the force or electric field into the component at origin where the fifth charge is placed.
Any how you have to present your requirment in order to get complete answer.
