1500 joules
The word in your question that I keyed on is "resting". An object at rest has zero kinetic energy. If you meant potential energy, the answer is 1500 joules.
The kinetic energy of the object at rest on the edge of the cliff is zero because there is no motion.
The gravitational potential energy gained by lifting a 1 Newton book 4 meters is 4 Joules. This is calculated by multiplying the force (1 Newton) by the distance (4 meters) to get the energy in Joules.

The kinetic energy of the object when it is still at rest on the edge of the cliff is zero because it has no motion. Kinetic energy is the energy possessed by an object due to its motion, so as long as the object is stationary, it has no kinetic energy.

Force x distance = 100 x 2 = 200 newton-meters = 200 joules.

potential energy = mass x gravity x height.Gravity is measured in units of acceleration.Specifically in the case of SI units:Energy is measured in joule.Mass is measured in kilograms.Gravity is measured in meters/second2, or the equivalent newton/kilogram. The numeric value is approximately 9.8 in either case.Height is measured in meters.
The potential energy gained by the book can be calculated using the formula: potential energy = mass * gravity * height. The mass of the book is needed to calculate the exact amount of potential energy gained. Assuming a mass of 1 kg, the potential energy gained would be approximately 39.2 J.

Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)
The way I understand it, torque is unrelated to energy, despite the fact that torque and energy happen to have the same dimensions, namely force x distance (in units: newton x meters). In other words, torque is not an energy; it is a different kind of measurement.
