Question

2 springs A and B with constants KA and KB
(KA is greater than KB) are given In which of
the spring more work is to be done if they are stretched, (a) by
same amount (b) by same force

Shikha Bhadoria · Accepted Answer

F=-kxW=∫F dx=∫0x(-kx)dx=12kx2 So, clearly if (a) x is same: W will be more for higher value of K As KA>KB =>WA>WB (b) And if same force is applied, as KA>KB => the displacement 'x' of A will be lesser xA

2 springs A and B with constants KA and KB (KA is greater than KB) are given. In which of the spring more work is to be done if they are stretched, (a) by same amount (b) by same force.

2 springs A and B with constants K_{A^{and K}B}(K_Ais greater than K_B) are given. In which of the spring more work is to be done if they are stretched, (a) by same amount (b) by same force.
