Question

Two point masses are separated by a distance 10cm. the potential at a point 2cm from m1 is(m1=2g ; m2=8g​

Answer 1

Answer:

10J

Explanation:

Given, m1=1kg,m2=4kg,r=10cm=10×10−2m

∴ Gravitational potential energy

U=−Gm1m2r=−6.67×10−11×1×410×10−2=−26.68×10=10J

The potential energy that a huge item has in relation to another massive object due to gravity is known as gravitational energy or gravitational potential energy. When two objects descend toward one another, the potential energy associated with the gravitational field is released (transformed into kinetic energy). Bringing two things farther apart increases the gravitational potential energy.

The gravitational potential energy exists for two pairwise interacting point particles. In classical mechanics, the gravitational potential between two or more masses is constant. In accordance with the principle of energy conservation, the gravitational field energy must always be negative, such that it is 0 when the distance between the objects is infinite. [2] The potential energy that an object has as a result of being in a gravitational field is known as gravitational potential energy.
