Question

spring of spring constant 8n as an extension find the minimum work done in increasing the extension for 5 centimetres to 15 cm is??tell me​

Answer 1

Answer:

The work done is stored as elastic potential energy in the spring. Therefore, The work done in extending it from 5cm to 15cm is 8 J. = 8N/cm.

Explanation:

hope it's help you

Answer 2

Considering spring constant as 800N/cm

Work done in extending a spring = 1/2kx²

Therefore, work done in extending spring from 5cm to 15cm

= 1/2 × 800 × (15² -5²)

= 400×(225-25)

=400×200 N cm

= 8 × 10⁴ N cm

= 800 N m
