If the gravitational field strength at a point is 10 N/kg, what is the gravitational potential at that point assuming it is zero at infinity?
-10 J/kg
-5 J/kg
0 J/kg
10 J/kg
The gravitational potential V is related to the gravitational field strength g by V = -g * r. If we consider r to be 1 meter, V = -10 * 1 = -10 J/kg.

Q
Q: If the gravitational field strength at a point is 10 N/kg, what is the gravitational potential at that point assuming it is zero at infinity?
Solution: The gravitational potential V is related to the gravitational field strength g by V = -g * r. If we consider r to be 1 meter, V = -10 * 1 = -10 J/kg.
Steps: 5
Step 1: Understand that gravitational field strength (g) is given as 10 N/kg.
Step 2: Know that gravitational potential (V) is calculated using the formula V = -g * r.
Step 3: Choose a value for r (the distance from the point to the center of the mass causing the gravity). Here, we will use r = 1 meter.
Step 4: Substitute the values into the formula: V = -10 N/kg * 1 m.
