Question

(a) Plot ?(?) = $\frac{ABC}{X^{2}}$ , where ? = 1, ? = 5 and ? = 2.

(b) What happens to ?(?) as ? increases? Decreases?

(c) Now let ? = −2. Plot ?(?) again.

(d) What in physics behaves like this?

Comment: "If possible. I'd like to know the how and why on some steps, please. Thanks"

Answer 1

a) We have $f(x)=10/x^{2}$ in the case when C=2.

When C=-2,$f(x)=-10/x^{2}$.

The 2 graphs are plotted below.

b) For the case of y=10/x², when x increases, y decreases while when x decreases , y increases.

d)The gravitational and the electrostatic forces behave like this in Physics.
