Answer:
Explanation:
As we know that for perfectly elastic collision total mechanical energy is always conserved
so we will have
now we also know that total moment of the system is conserved in any collision because there is no external force on it
so we will have
Answer:
<h2>2 kg</h2>Explanation:
The mass of the object can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>2 kg</h3>Hope this helps you
Force on the particle is defined as the application of the force field of one particle on another particle. the electrical force between q₁ and q₃ will be –1. 1 × 10¹¹ N.
<h3>What is electric force?</h3>Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.
The electric force in the second case will be the same as in the first case. Therefore the force on the particle will be the same.
Hence the electrical force between q₁ and q₃ will be –1. 1 × 10¹¹ N.
