Question

Place the charge q= 2.10-5c at the origin o of the oxy-axis system. consider two points a(6;0) and b(3;4) on the axes with unit of measurement in cm. choose the potential origin at infinity. calculate the work done by the electric field when moving the charge q=-1uc from a to b

Answer 1

The work done by the electric field when moving the charge from a to b is 0.0378 J.

Distance between a and b

r = √[(a₂ - a₁)² + (b₂ - b₁)²]

r = √[(3 - 6)² + (4 - 0)²]

r = 5 m

Work done in moving the charge

W = Fr

W = kq₁q₂/r

W = (9 x 10⁹ x 2.1 x 10⁻⁵ x 1 x 10⁻⁶)/(5)

W = 0.0378 J

Thus, the work done by the electric field when moving the charge from a to b is 0.0378 J.
