Find the PE of a 25kg object 167 m above the surface of the

Find the PE of a 25-kg object 1.67 m above the surface of the National Mail in Washington, DC. Take the surface on Tiananmen Squarer to be zero potential. Possibly useful information Beijing elevation:43 m above sea level. National Mail elevation 10m above se level Radius of the Earth: 6.38 times 10^5 m. Assume that DC and Beijing are directly opposite each other for this problem. -8100 J -7700 J 410 J 3.1 times 10^9 J

Solution

Solution :

Potential energy is nthing but the energy posessed by a body due to its mass and position.

Given that the position is 1.67 above the surface , e need to calculate the Potental energy using the formula

P.E = m*g*h

P.E = 25*1.67*9.81 = 410 J
