Question

find the solid angle subtended at the Periphery of an area of 2 cm square at a point situated symmetrically at a distance of 6cm from the area

Answer 1

Given:

The Periphery of an area of 2 cm square at a point situated symmetrically at a distance of 6cm from the area.

To find:

Find the solid angle subtended at the Periphery of an area of 2 cm square at a point situated symmetrically at a distance of 6cm from the area

Solution:

From given, we have,

The Periphery of an area of 2 cm square at a point situated symmetrically at a distance of 6cm from the area

The formula used to calculate the solid angle subtended is as follows:

dw = ds/r²

dw = 2 cm² / (6 cm)²

dw = 2/36

dw = 0.055 steradian

Therefore, the solid angle subtended at the Periphery is 0.055 steradian
