In the process of mitosis (cell division), two motor proteins pull on a spindle pole, each with a 7.4pN -force. The two force vectors make a 68 degrees angle.
What's the magnitude of the force the two motor proteins exert on the spindle pole?

-
the resultant force is FR = square root of [ F^2 + F^2 + 2 F^2 cos(68) ]
= 2 F cos(theta/2) = 2 x 7.4 x10^-12 x cos( 34) = 14.8 x0.829x10^-12
= 12.27 pN.
= 2 F cos(theta/2) = 2 x 7.4 x10^-12 x cos( 34) = 14.8 x0.829x10^-12
= 12.27 pN.
