Question

The pointer reading v/s load graph for a spring balance is as given in the figure. The spring constant is ______.

Options

• 0.1 kg/cm

• 0.04 kg/cm

• 40 kg/cm

• 15 kg/cm

Answer 1

The pointer reading v/s load graph for a spring balance is as given in the figure. The spring constant is 0.04 kg/cm.

Explanation:

Spring constant, k = `"F"/"x"` = Slope of curve

` therefore "k" = (800 - 200)/15`

= 40 g/cm = 0.04 kg/ cm
