Question

Pick out the wrong statement from the following

• A. The SI unit of universal gravitational constant is $\text{Nm}^2\text{kg}^{-2}$
• B. The gravitational force is a conservative force
• C. The force of attraction due to a hollow spherical shell of uniform density on a point mass inside it is zero
• D. The centripetal acceleration of the satellite is equal to acceleration due to gravity
• E. $\text{Gravitational potential energy} = \frac{\text{gravitation potential}}{\text{mass of the body}}$

Hint:

Always remember: "Potential" is like "price per kg," and "Potential Energy" is the "total cost". To get the total cost, you multiply the weight by the price!
