Which of the following pairs has the same direction always?
Correct answer: C. Force, acceleration
- A. Force, displacement
- B. Force, velocity
- C. Force, acceleration
- D. Force, momentum
Explanation
According to second law of motion when force is applied on a body acceleration is produced in it in the same direction. Therefore, option C is correct.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
