The force excerted by a charged body on another body is known as gravitional force?? true ya false?? |
|
Answer» Answer : False Explanation : ⇒ The force exerted by a charged BODY on another body is known as Electrostatic force or Coulomb force. ⇒ GRAVITATIONAL force operates among all objects in the universe. ⇒ Electrostatic force operates among charged particles. ⇒ The magnitude of electrostatic force b/w two point charges is directly proportional to the PRODUCT of charges and inversely proportional to the square of the DISTANCE b/w them. This is known as Coulomb's law also known as inverse square law. ⇒ Coulomb force and gravitational force follow the same inverse-square law. But gravitational force is always attractive, while Coulomb force can be bot attractive and repulsive, allowing possibility of cancellation of electric forces. ⇒ The law of gravitation is universally valid. It applies to small objects on the earth, planets in the solar SYSTEM and to galaxies. |
