if welift a body of mass 70g vertically upwards 10m then calculate the force requried to lift the body (g=10ms-2)?

Open in App

Solution

The force would simply be equal to the weight of the body.
W = mg
m = 70 g = 70/1000 kg [Always convert into SI units]
g = 10 m/s2
You can calcuate the final answer by using the formula given above.
