Question

what is the force constant of a spring which is stretched a)2mm by a force of 4N
b 4cm by a mass of 200g

Answer 1

Answer:

(a) Force=spring constant × displacement

$f = spring constant \times 2 \times {10}^{ - 3}$

$spring \: constant = 4 \div 2 \times {10}^{ - 3}$

spring constant =2000N
