In the opposite corners of a square there are two identical ions. Each has a charge of +e. The length of one side of the square is L. What is the net electric potential caused by the two positive ions at both of the empty corners of the square?

a)ke/2L
b)ke/L
c)2^.5(ke/L)
d) 2ke/L

Which chapter in physical science?

anonymous · Answer

um well i don't know what book you use, but its ch  23 in our book. Young and Freedman University Physics 13th edition

Nevermind then. Your school is way much different then mine.

anonymous · Answer

ok then

anonymous · Answer

its d) because net potential=sume of electric potential where direction doesn't matter. so,    
ke/l+ke/l=2ke/l

Thank you @physo
