The correct answer is
A) true
In fact, the electrical force can be present only if the two objects have a net charge different from zero, because the electrical force is proportional to the value of the charges:
so, if they are neutral they cannot exert an electrical force between each other, because their charge Q is zero.
Viceversa, the gravitational force is always present when the objects have masses, since the force is proportional to the value of the masses:
so, even if the two objetcs are neutral, if they have mass, they exert a gravitational force to each other.
Answer:
Explanation:
The corona virus Vaccine will have some side effects like soreness in injection area but this will only last for a couple of days. I believe the answer is that there is no long term affect.
The point on a line through the ends of the meter stick is the electric field equal to zero is 4.7 m from the 0 cm mark.
<h3>What is electric field?</h3>
An electric field is the physical field that surrounds the electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It also refers to physical field for a system of charged particles. Electric fields originate from the electric charges and time-varying electric currents. Electric fields and the magnetic fields are both manifestations of the electromagnetic field, one of the four fundamental interactions (also called forces) of nature.
Electric fields are important in many areas of the physics, and are exploited in electrical technology. In atomic physics and chemistry, for the instance, the electric field is the attractive force holding the atomic nucleus and electrons together in atoms. It is also force responsible for chemical bonding between atoms that result in molecules.
The electric field is defined as a vector field that associates to each point in the space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point. The derived SI unit for electric field is the volt per meter (V/m), which is equal to the newton per coulomb (N/C)

The correct question will be:
"A +5.00-μC point charge is placed at 0.0 cm mark of meter stick and a -4.00-μC point charge is placed at 50.0 cm mark. At what point on a line through the ends of meter stick is electric field equal to zero?"
Answer:
1) 20 m/s
2) 60 meters
Explanation:
with a constant acceleration of 4m/s/s, the vehicle will end up traveling at 20 m/s after 5 seconds, and will have travelled 60 meters.
Hey there! <span>The cohesive forces between liquid molecules are responsible for the phenomenon known as </span>surface tension<span>. The molecules at the </span>surface do<span> not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the </span>surface<span>. Hope this helps! :)</span>
