Answer:
3.2 × 10⁻⁸ N.
Explanation:
By Coulomb's Law, the magnitude of the electromagnetic force between two point charges is inversely proportional to the square of their separation, . In other words,
.
- Initial electromagnetic force ;
- Initial Separation ;
- Final Separation .
Final electromagnetic force:
.
The guy at the top, controlling the drop and making the heavy containr drop slowly, is doing <em>negative work</em>.
He's exerting force upward ... opposite to the direction the container is moving. So the product of (force) x (distance) is negative. He's controlling the potential energy that the container had when it left the second floor, and making sure that the container reaches the ground with <u><em>zero kinetic energy</em></u>.
-- The guy in the window holding the rope is doing <u><em>negative</em></u> work.
-- Gravity is doing the <u><em>positive</em></u> work.
The cones present on the retina are the cells that help you see the colors.....there are mainly three types....red blue and green, cones but they mix to generate different colours !
Hello!
Let's put it into symbols:
Change in velocity =
A measurable interval:
This division is:
We can recognize this as the
Average Acceleration
The general equation for voltage, field strength and distance is
<u>Explanation:</u>
Electric field is the measure of potential crossing per unit distance. In other terms we can say it as the work done to displace the charge from infinity to a point and the potential difference between them. The unit of Electric field is written as V/m, it is also known as field strength.
So the field strength is directly proportional to the potential and inversely proportional to the displacement or the distance covered by the charge. Thus, is the general equation relating voltage, field strength and distance.
