A 100 W light bulb is placed at the centre of a spherical chamber of radius 0.10m. Assume that 66% of the energy supplied to the bulb is converted into light and that the surface of chamber is perfectly absorbing. The pressure exerted by the light on the surface of the chamber is

View answer and explanation

Correct option: B

1.77 \times {10^{ - 6}}

Pa

Option B (

1.77 \times {10^{ - 6}}

Pa) is correct because it is the pressure exerted by the light calculated using the formula for radiation pressure.
