A variable force F acts along the X-axis given by
F = (3x 2 – 2x + 1) N. The work done by the force when a particle of mass 100 g moves from
x = 50 cm to x = 100 cm is -
Text Solution
Verified by ExpertsThe correct answer is:
A
= 
= 
= (1 – 0.5 3 ) – (1 – 0.5 2 ) + (1 – 0.5)
= (1 – 0.125) – (1 – 0.25) + (0.5)
= 0.875 – 0.75 + 0.5
=0.625
