Question

The magnitude of potential energy per unit mass of an object at the surface of earth is E, then
the escape velocity of the object is​

Answer 1

Answer:

Please mark my answer as brainlest and also please follow me

Explanation:

Escape velocity = root(2gR) = 11 kms on earth

When an object achieves it's escape Velocity then it's mechanical energy (P.E + K.E) = 0
