The genotype for all offspring will be Pp making the flower color white.
Answer:
Torque = R X F = R * F sin theta
-f * 2R will exert an equal opposite torque
-f * 2 = F sin theta
f = -F sin theta / 2

Explanation:
It is given that,
The thinnest soap film appears black when illuminated with light with a wavelength of 535 nm, 
Refractive index, 
We need to find the thickness of soap film. The soap film appear black means there is an destructive interference. The condition for destructive interference is given by :

t = thickness of film
m = 0,1,2....
= refractive index


For thinnest thickness, m = 1


Hence, this is the required solution.
