Electrostatic potential energy of a system of charge is given by
here we have
= two charges of different magnitudes
r = distance between charges
so here we can see that electrostatic potential energy will depends upon the product of two charges and inversely depends upon the distance between the two charges
So here we can say that the electrostatic potential energy of two charges will be same and equal to each other
Answer:
1. As rocket mass increases, acceleration decreases.
2. The inverse of the mass of the boat.
Explanation:
1. Newton's second law of motion states;
F = ma
where F is the force applied, m is the mass and a is the acceleration.
Therefore, increasing the mass of a rocket increases its weight which would reduce its acceleration provided that the force is constant. Thus, as rocket mass increases, acceleration decreases.
2. The slope of the graph can be expressed as;
From Newton's second law,
F = ma
Slope = (Δa) ÷ (ΔF)
Slope =
⇒ =
Therefore, the slope of the graph is the reciprocal of the mass of the boat.
