I guess i made a mess of this just learning equations and already finding it stressful. Dont worry thanks for help any way was following system we have been given to do equation clearly not very effective. :rolleyes:
first i thought that swaping side over then wasnt sure what i should do with square root
F = A Q1Q 2 / r2
A Q1Q2 / r2 = F
A Q1Q2 / r2 x Q1Q2 / r2 = F Q1Q2 / r2 x Q1Q2 / r2
A = F Q1Q2 / r2
this all seems abit bulky.
