Homework Statement At the vertices of a triangle there are + 5C, -7C, -3C of charge respectively. What is the electric intensity and direction at its orthocentre? Homework Equations Each side of the triangle is 1 mm in length. The Attempt at a Solution [/B] I failed to find the distance of...

Y Yes.You are absolutely correct :) Thank you.

But the critical part may be how you will find the final equation.But it is easy too.

The shortest way is circuit symmetry which provides Equivalent Resistance= 11R/20 here R=2. hence equivalent R=1.1 ohm. This was so simple.

Can you calculate the equivalent resistance please .I am getting 1.43 ohms and 1.6 ohms as the answer in different cases. Can you tell me the answer, please :3

Then what will be the equivalent resistance?

Is there any other way?
