Electric potential : MCQ ON ELECTRIC POTENTIAL

Electric potential is defined as the amount of work needed

to move a unit charge from a reference point to a specific

point against the electric field.

Q1 Electric potential is

• Scalar quantity 
• vector quantity 
• Both 
• None

• Scalar quantity 

 

Q2 One volt is equivalent to 

• Newton/second 
• Newton/coulomb 
• joule/coulomb
• joule/coulomb

• joule/coulomb

Q3 Electric potential due to electric dipole at a point on its equatorial line is always

• Zero 
• one 
• infinity 
• none

• Zero 

Q4 Electric potential inside conductor is 

• Same 
• zero 
• None
• may or may not zero 

• Same 

Q5 Electric potential due to electric dipole at a point on equatorial line is zero(T/F) 

• True
• False

• True

Q6 The electric potential on Equipotential surface is same

• True
• False 

• True

Q7 What is the nature of equipotential surfaces in case of a positive

charge? 

• Circular 
• Spherical 
• Cubical 
• Cylindrical

• Circular 

Q8 The nature of equipotential surfaces due to point charge, situated at infinity  is  

• Circular 
• Spherical 
• Cubical 
• Plane 

• Plane 

 

Q9 Electric field is steepest in the direction in which the potential...

• Remain constant
• Increases
• Either decreases or remain constant
• decreases

• decreases 

Electric field is defined as the negative of the gradient, i.e.

E=-δV/δr it points in the direction of steepest descent of the potential.

Q10 Work done in moving a charge over an equipotential surface is zero.(T/F)

• True
• False

• True

Q11 What is the direction of electric field with respect to equipotential surface?

• `0^{0}`
• `90^{0}`
• `60^{0}`
• `45^{0}`

• `90^{0}`
