Question
Same spring is attached with 2kg, 3kg, and 1kg blocks in three different cases as shown in figure . If X1, X2 , and X3 be the extension in the spring in these three cases then
Options
A. x1 = 0, x2 > x3
B.x2 > x1 > x3
C.x3 > x1 > x2
D.x1 > x2 > x3
Solution
In (A) T = kx1 = 2g
In (B) T = kx2 = 3g - 3 ×
In (C) T = kx3 = 2g - 2 ×
In (B) T = kx2 = 3g - 3 ×
In (C) T = kx3 = 2g - 2 ×
