Answer:
Thus, the restoring force is - 12 a b.
Given:
Spring constant = 4 a
Stretched displacement = 3 b
To find:
Restoring force = ?
Formula used:
The restoring force is given by,
F = -k x
Where F = restoring force
spring constant = k = 4 a
stretched displacement = x = 3 b
Solution:
The restoring force is given by,
F = -k x
Where F = restoring force
spring constant = k = 4 a
stretched displacement = x = 3 b
F = - (4 a) (3 b)
F = - 12 a b
Thus, the restoring force is - 12 a b.
