Net force = Pull force - Friction (Opposing force) = 700 - 215 = 485 N
Answer:
The work function is 
Explanation:
From the question we are told that
The light energy is 
The stopping voltage is 
Generally work function is mathematically represented as

Where KE is the kinetic energy of the ejected electron and it is mathematically represented as

Where e is the charge on the electron
So

Thus

=>
