In a recent pool of 500 men and 500 women
it was observed that a total of 650 were married.
of those married 275 were men and 500

(i)the number of married who
are unhappy.
(ii)the number of married who
are happy.
Please can someone help with a

In a region an electric field exist in a given
direction and it passes through a circle
of radius R normally. The magnitude
of electric field is given as :
E = E_0 (1− (r/R)). where r is the distance
from centre of circle .Find electric
flux through plane of circle within it.
please is there any general way for
calculating the error or uncertainty
in g when
m=((4π^2 )/g) where m=slope and
g=acceleration due to gravity
