Arrange the four graphs in descending order of total work done; where W 1, W 2, W 3 and W 4 are the work done corresponding to figure a , b , c and d respectively.

Question

Arrange the four graphs in descending order of total work done; where W 1, W 2, W 3 and W 4 are the work done corresponding to figure a , b , c and d respectively. (A) W3>W2>W1>W4 (B) W 3> W 2> W 4> W 1 (C) W 2> W 3> W 4> W 1 (D) W 2> W 3> W 1> W 4

Work done = area under F - x curve. Area below x- axis is negative area above x-axis is positive. So W 3> W 2> W 1> W 4

Q. Arrange the four graphs in descending order of total work done; where $W_{1}, W_{2}, W_{3}$ and $W_{4}$ are the work done corresponding to figure $a, b, c$ and $d$ respectively.

$W_{3} > W_{2} > W_{1} > W_{4}$

$W_{3} > W_{2} > W_{4} > W_{1}$

$W_{2} > W_{3} > W_{4} > W_{1}$

$W_{2} > W_{3} > W_{1} > W_{4}$

Work done $=$ area under $F - x$ curve. Area below $x -$ axis is negative & area above $x$ -axis is positive.
So $W_{3} > W_{2} > W_{1} > W_{4}$

Q. Arrange the four graphs in descending order of total work done; where W1​,W2​,W3​ and W4​ are the work done corresponding to figure a,b,c and d respectively.

W3​>W2​>W1​>W4​

W3​>W2​>W4​>W1​

W2​>W3​>W4​>W1​

W2​>W3​>W1​>W4​
