Option a; Electric field can accelerate an electron, but never change its speed
An electric field (also known as an E-field) is a physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It can also refer to the physical field of a charged particle system. Electric fields are created by electric charges and time-varying electric currents. Electric and magnetic fields are both aspects of the electromagnetic field, one of nature's four fundamental interactions (also known as forces). Electric fields are significant in many areas of physics and are used in electrical technology. In atomic physics and chemistry, for example, the electric field is the attractive force that holds the atomic nucleus and electrons together in atoms. It is also the driving force behind chemical bonds between atoms.

Answer:
Explanation:
The force is defined as the negative of the derivative of the potential energy:
If we use the potential energy function given in this problem:
and we calculate the force, we get:
So, the force is
Answer:
Attractive
Explanation:
Data provided in the question
The potential energy of a pair of hydrogen atoms given by 
Based on the given information, the force that one atom exerts on the other is
Potential energy μ =
Force exerted by one atom upon another
or
or
As we can see that the 
comes in positive and constant which represents that the force is negative that means the force is attractive in nature
Answer:
when they have the same slope
Answer:
heat energy that is needed to raise tempeture
