REPLAY - Two Sides of the Same Story

Basic proportionality Theorem or Thales Theorem - If a line is drawn parallel to one side of a triangle intersecting the other two sides; then it divides the two sides in the same ratio.

Two wires of the same length are shaped into a square of side 'a' and a circle with radius 'r'. If they carry same current, the ratio of their magnetic moment is

What is your stance regarding the two endings to the Roger Skunk story?

Two positive charges of magnitude q are placed at the ends of a side ( side 1) of a square of side 2a . Two negative charges of the same magnitude are kept at the other corners . Staring from rest , n a charge Q moves from the middle of side 1 to the centre of square , its kinetic energy at the centre of square is -.

Prove that , "If a line parallel to a side of a triangle intersects the remaining sides in two distinct points then the line divides the sides in the same proportion".
