Calculate the solid angle subtended by the periphery of an area of 1 cm^(2) at a point situated symmetrically at a distance of 5 cm from the area.

Calculate the solid angle subtended by the periphery of an area of 1 c

1.	Calculate the solid angle subtended by the periphery of an area of 1 cm^(2) at a point situated symmetrically at a distance of 5 cm from the area.
Answer» SOLUTION :SOLID angle `Omega=("Area")/(("Distane"^(2))` `=(1 cm^(2))/((5 cm)^(2))=(1)/(25)=4xx10^(-2)SR`
