Q: The gravitational potential at a point is defined as the work done in bringing a unit mass from infinity to that point. What is the unit of gravitational potential?
Solution: The unit of gravitational potential is Joules per kilogram (J/kg).
Steps: 5
Step 1: Understand that gravitational potential is related to work done.
Step 2: Recall that work is measured in Joules (J).
Step 3: Recognize that gravitational potential is defined per unit mass.
Step 4: Know that mass is measured in kilograms (kg).
Step 5: Combine the units: since gravitational potential is work done (J) per unit mass (kg), the unit becomes Joules per kilogram (J/kg).
