Answer:
45.6m
Explanation:
The equation for the position y of an object in free fall is:
With the given values in the question the equation has one unknown v₀:
Solving for t=1:
1)
To find the hight of the tower you can use the concept of energy conservation:
The energy of the body 1 sec before it hits the ground:
2)
If h is the height of the tower, the energy on top of the tower:
3)
Combining equation 2 and 3 and solving for h:
4)
Combining equation 1 and 4:
The charge on the positive plate is 1.734* C
Given,
V=9v, R=0.066m Gap(G)=2.0mm=0.0020m ∈=8.85*
We know C=∈ * = 8.85*
*
=19.275*
F
Also, Q = C V = 19.275* * 9 = 1.734*
C
When charged matter is exposed to an electromagnetic field, its electric charge—a property of matter—causes it to feel a force. A charge on an electric field might be positive or negative. Like and unlike charges are attracted to one another while being repelled by the other. Neutral describes a thing without any net charge. Electric charge is a conserved property; in an isolated system, the net charge, or the sum of the positive and negative charges, is constant. Subatomic particles transport electrical charge. The protons in atoms' nuclei carry positive charge in normal matter, while the electrons carry negative charge.
