Answer:
The work that has been done by the electric force is 1.36 x 10⁻²⁰ J
Explanation:
given information:
electric potential, V = 0.085 V
we can use the following formula to calculate the electric force of sodium
W = - eΔV
where
W = work (joule, J)
e = charge (coulomb, C)
V = electric potential (volt, V)
The charge of sodium ion is 1.6 x 10⁻¹⁹. Therefore,
W = - eΔV
= - (1.6 x 10⁻19 C) (-0.085)
= 1.36 x 10⁻²⁰ J
