A 10 kg object is located 2 meters above the ground. The object's gravitational potential energy relative to the ground is:

A. 19.6 J
B. 196 J
C. 98 J
D. 512 J
E. 1024 J

Answer :

Final answer:

The gravitational potential energy of a 10 kg object located 2 meters above the ground is 196 Joules. This is calculated using the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height.

Explanation:

The gravitational potential energy (U) of an object relative to the ground is calculated using the formula:

U = m * g * h

Where:

U is the gravitational potential energy.

m is the mass of the object (10 kg).

g is the acceleration due to gravity (approximately 9.81 m/s² on Earth).

h is the height above the ground (2 meters).

Substituting the values into the formula:

U = 10 kg * 9.81 m/s² * 2 m = 196.2 J

So, the object's gravitational potential energy relative to the ground is approximately 196.2 Joules, which is closest to option (b) 196 J.
