What is the gravitational field strength (g) at a distance r from the center of a planet of mass M? (2023)
Step 1: Understand that the gravitational field strength (g) is a measure of the force of gravity experienced by an object at a certain distance from a planet's center.
Step 2: Identify the variables in the formula: G is the gravitational constant, M is the mass of the planet, and r is the distance from the center of the planet.
Step 3: Recognize that the formula for gravitational field strength is g = GM/r^2.
Step 4: Remember that 'r' should be the distance from the center of the planet to where you want to calculate the gravitational field strength.
Step 5: Plug in the values for G, M, and r into the formula to calculate g.
