Question

Three point charges 1c,2c,and 3c are placed at the
corners of an equilateral triangle of side 1m.
Calculate the work required to move these
charges to the corners of a smaller
Equilateral triangle of side 0.5m?

Answer 1

Answer: 0.342cm² (approx)

Explanation:

Required area of equilateral triangle =area of large equilateral triangle - area of small equilateral triangle

=(root3/4) A²-(root3/4) a²

=root3/4[(1)²-(0.5)²]

=root3/4(1-0.25)

=root3/4(0.75)

=0.324cm² (approx)

Hence the required area is 0.324(approx)
