# An electricity and magnetism problem by Ronak Agarwal

Find the force on a uniformly charged hollow sphere of radius $$1m$$ and surface charge density $$\sigma = 0.5\quad \mu C/{ m }^{ 2 }$$ by a point sized particle of charge $$q={ 10 }^{ -3 }$$ columbs placed at a distance $$5 m$$ from the centre of the sphere

Take $${ \varepsilon }_{ 0 }$$$$= 8.85\times { 10 }^{ -12 }\quad { C }^{ 2 }/N{ M }^{ 2 }$$
