Answer: B) Zinc will act as Anode
Explanation:
Standard reduction potential of zinc and nickel are:
Here Zinc undergoes oxidation by loss of electrons, thus act as anode as it has more negative reduction potential.
Nickel undergoes reduction by gain of electrons and thus act as cathode. as it has less negative reduction potential.
Where both are standard reduction potentials.
As the emf is positive, the reaction is spontaneous and reaction will occur.
Thus Zinc will act as anode.
Answer with Explanation:
Electric field:It is the force per unit charge experienced by rest charge at any given point.
It is the area around the charge which is placed at rest.It is represented by E.
Mathematical formula:
Magnetic field:It is an area around moving charge in which moving charge particle experienced magnetic force in that area.
Magnetic field is represented by B.
Mathematical formula :
Where B=Magnetic field
q=Charge on particle
v=Velocity of particle
F=Magnetic force exert on particle
