Thanks, tim. I understand it now.

The relation V=Ed is true only for a region of uniform electric field and does not apply here. Assume a test charge Q at the centre of the arrangement, find the potential energy of this test charge , a multiple of Q. Divide by Q to get the potential at the centre. Use potential energy = (Qq1...

Three springs of spring constant kare connected to a body of mass m and rigid supports, so that the angles are A 90 degrees between two and 135 degrees between each of these two and the third. B 120 degrees between any 2 adjacent ones. Find time period of vibration. I worked out a...
