A particle of mass 100 g is thrown vertically upwards with a speed of 5 m/s. The work done by the force of gravity during the time the particle goes up is:
Text Solution
Verified by ExpertsThe correct answer is:
B
: The height (h) traversed by particle while going up is:
h = 
= 
Work done by gravity force = 
= 
= 0.1 × g × 
(Angle between force and displacement is 180°)
W = – 0.1 × 
= – 1.25 J
