A wire suspended vertically from one of its end

Asked by admin @ in Physics viewed by 272 People

A wire suspended vertically from one of its ends is stretched by attaching a weight of 200n to the lower end. The weight stretches the wire by 1mm. Then the elastic energy stored in the wire is

Answered by admin @


Energy = 1/2 × Force × Extension

E = 1/2 × 200N × 1 mm

E = 100N × 0.001m

Therefore, E = 0.1J
