Answer: Power of a lens is -2D, negative sign indicates it is a Concave lens. Focal length (in meters)=1/power of the lens, thus focal length=1/2=0.5m=50cm.Jul 6, 2019
The force that the spring exerts is 1.31 N.
<h3>What is Spring force?</h3>
- The displacement (compression or expansion) and force constant of the specific spring determine the spring's force.
- It always takes action to get mass back to where it should be for equilibrium.
- The force applied to the spring and the energy it has stored are shown in the formulas below:
F = kx
Where,
x = displacement in the spring
k = spring force constant
<h3>Calculation of spring force:</h3>
Given,
k = 8.75 n/m
x = 0.150 m
Force exerted by the spring, F = kx
putting the values,
F = 8.75 x 0.150
= 1.3125 N
Hence, the force that the spring exerts is 1.31 N.
