Answer:
Therefore the magnitude of required electric force is 292.864×10⁻⁵ N.
Explanation:
The number of proton of iron is 26.
C is the charge of each proton.
Total charge of 26 proton is =(26×1.6×10⁻¹⁹) C
=41.6×10⁻¹⁹ C
The charge of innermost electron is = - C
Coulomb's Law:
The attraction or repulsion force of two charges is
- directly proportional to the product of the charges.
- inversely proportion to the square of distance
Let 
be two positive charge and the distance between the charges be r
Then F∝
and 
Therefore,
Here
= - C and 
=41.6×10⁻¹⁹ C
r = 1.5× 10⁻¹² m
K= 9.9× 10⁹C²N⁻¹m⁻²
Therefore
N
= -292.864×10⁻⁵ N
The mins sign shows the direction of the force.
Magnitude of electric force is only the numerical value of the force.
Therefore the magnitude of required electric force is 292.864×10⁻⁵ N.
Explanation:
32. The area under the curve from t = 0 and t = 2 is the area of the triangle. The base of the triangle is 2 seconds, and the height of the triangle is 2 m/s. The area is therefore:
A = ½ bh
A = ½ (2 s) (2 m/s)
A = 2 m
33. The car is not moving when the velocity is 0 m/s. This occurs at t = 0, t = 6, and t = 10.
Dew point is the temperature at which the water vapor in the air condenses , then evaporates. The barometric or air pressure is independent from the dew point.
Answer:
Please see below as the answers are self-explanatory.
Explanation:
1) The resultant force is along the line that joins both charges or both masses (assuming both objects can be represented as points)
2) Both type of forces obey Newton's 3rd law.
3) Both are proportional to the product of the property that is affected by the force (charges and masses)
4) Both obey an inverse - square law (consequence of our universe being three-dimensional)
1) Main difference, is that while the gravitational force is always attractive, the electrostatic force can be attractive or repulsive, as there are two types of charges, which attract each other being of different type, and repel each other if they are of the same type.
2) It is possible, artificially, to block the influence of the electrostatic force, shielding a room, for instance, which is not possible for the gravitational force.
