A +7.5 nC point charge and a -2.0 point charge are 3.0 cm apart. What is the electric field strength at the midpoint between the two charges?
just give me the formula ?
just give me the formula ?
jokester4u said:whts is q ? and how do i find q from the question ?
jokester4u said:can you tell me the exact way to solve it ?
Electric field intensity is a measure of the strength of an electric field at a particular point in space. It is a vector quantity, meaning it has both magnitude and direction.
The electric field intensity at a point is calculated by dividing the force exerted on a positive test charge at that point by the magnitude of the test charge.
The unit of electric field intensity is newtons per coulomb (N/C) in the SI system. In the cgs system, it is measured in dynes per statcoulomb (dyn/statC).
According to Coulomb's Law, electric field intensity is inversely proportional to the square of the distance between two charges. This means that as distance increases, electric field intensity decreases.
Electric field intensity plays a crucial role in understanding and predicting the behavior of electric charges and how they interact with one another. It is also essential in the design and functioning of many electrical devices and technologies.
