Actually Welcome to the Concept of the Electrostatics.
Basically here we can see that, the Negative test charge usually a Electron is facing a force from the right side, this we can say that a Electric field as like charge is creating a repulsive force from the right to left side.
thus,
1) The electric field points to the left because the force on a negative charge is opposite to the direction of the field.
Albert Einstein was a German-born theoretical physicist. He developed the general theory of relativity, one of the two pillars of modern physics. Einstein's work is also known for its influence on the philosophy of science.
Answer:
Momentum is conserved.
All of the others are not conserved because of heat loss caused by deformation, etc.
The answer is attached below.
Let me know if you don't understand it and I'll explain even more for you ☺♥
