2. A stationary 0.325 kg steel ball begins rolling down a frictionless track from a height has shown in the diagram. It completes a loop-the-loop of radius 1.20 m with a speed of 6.00 m/s at the top of the loop. What is the gravitational
potential energy of the ball
at the top of the loop?

A. 0.98 J
B. 3.82 J
C. 5.85 J
D. 0 7.65 J

i think the answer would be reserve.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
