The x and y components of a certain force are measured and found to be Fx = (68 ± 3)N and Fy =(42 ± 2) N, respectively. Calculate the magnitude of this force? expressing your result to the proper number of significant figures.

Answer 1

the magnitude is

√(Fx^2 + Fy^2)

So, figure the min and max values for F and use the average ± something

Answer 2

i have no idea
