To claculate the gravitational attraction between two bodies with mass 1(m1) and mass 2 (m2) you need to use the equation:
F= G ((m1*m2)/r^2)
Where;
G is the gravitational constant (6.67E-11 m^3 s-2 Kg-1) and
r is the distance between the two objects.
Complete Question
Complete Question is attached below
Answer:

Explanation:
From the question we are told that:
Side length s=1.13m
Left field strength 
Right field strength 
Front field strength 
Back field strength 
Top field strength 
Bottom field strength 
Generally, the equation for Charge flux is mathematically given by

Where
Theta for Right,Left,Front and Back are at an angle 90

Therefore
with respect to Right,Left,Front and Back
Generally, the equation for Charge Flux is mathematically also given by
Where

Therefore

Most modern games have a sense of real-world physics, but not exactly perfect. In a video game, the realistic movement or action greatly depends on the precision of coding. In real life, movement isn't done or programmed by a strand of code.
Your presentation sounds interesting, being a gamer myself, I would look forward to it. But the choice lies in your hands. If you do reconsider, be sure you have a backup plan. Good luck to you.
(b)equation is not balanced
Answer:
Not possible, if we talk about real pyramids
Explanation:
There is no image shown in the question statement. However if we talk about the pyramids as we find them in Egypt, we cannot get a stable inverted pyramid because of the difficulty in terms of balancing it from its centre of mass. In theory one might balance the forces, but in actual, to balance all the load of the structure just on a point is extremely difficult.
However, the term inverted pyramid can be found in ecological system and also used as metaphors in English literature
