Answer:
C) 3.0
Step-by-step explanation:
Let the length of the other side be x.
Using Pythagoras theorem for right-angled triangle,
4.2^2=2.9^2+x^2
or,x^2=4.2^2-2.9^2
or,x^2=9.23
or,x=√9.23=3.0 units
Since we are to express the given conditions as a joint variation, we employ the use of k as our constant proportionality which we will denote in this item as k.
From the sentence,
F = kM₁M₂/d²
as we can see those in the denominator as those that vary inversely to the given parameter.
