11. Suppose a force F varies as the product of two masses, m and M, inversely as the square of the distance r between them. If F= 675 when m = 125, M = 225,
and r=0.0530, find the constant of proportionality k.
A. 61.48 X 10-10
B. 1.27X10-
C. 6.74 x 10-5
D. 6.76X10°
E. None

Step-by-step explanation:

Given

--- The variation

Required

Determine the constant of proportionality (k)

Express as an equation

Multiply both sides by

Make k the subject

Given that:

We have:

This can be represented as:

coin flip
