Awheel of mass 48 kg is lifted to a height of 0.8 m. how much gravitational potential energy is added to the wheel? acceleration due to gravity is g = 9.8 m/s2. a. 30.4 j b. 3.1 j c. 297.9 j d. 11,321 j

376.32 J

Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position.

m= mass of the body = 48 kg

g= acceleration due to gravity= ]

h= height of body= 0.8 m

the answer is a. at the equator

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
