What is the electric force from the rod on the point charge 'q'? Suppose that ( q = 17.5 , {nC} ) and ( l = 4.35 , {cm} ). Break the rod up into four equal pieces and use superposition to find the force.
a) ( F = /{k ⋅ q}/{4 ⋅ l²} )
b) ( F = /{k ⋅ q}/{l²} )
c) ( F = /{k ⋅ q}/{16 ⋅ l²} )
d) ( F = /{k ⋅ q}/{2 ⋅ l²} )
