Answer: The Electrostatic force of attraction or repulsion between two charges shows that the Newton's third law applies to electrostatic forces.
Explanation: Consider two Oppositely charged charges separated by distance d.
The electrostatic force exerted by charge 1 on charge 2 is.
By Coulomb's Law :
F1 = k .....................................(1)
The electrostatic force exerted by charge 2 on charge 1 is.
F2 = - k ................................. (2)
negative sign shows that force are in opposite direction.
From Equation 1 and 2
F1 = - F2
Which implies Newton Third law.
Answer:
Explanation:
Given
mass of lead piece
mass of water in calorimeter
Initial temperature of water
Initial temperature of lead piece
we know heat capacity of lead and water are and
respectively
Let us take be the final temperature of the system
Conserving energy
heat lost by lead=heat gained by water
