What is the x-component of the total electric field due to these two charges at a point on the x-axis?
1 answer:
Find the total x - component of the electric field at that point and get the resultant or the algebraic sum.
- The electric field is a vector as it gives the force on a unit positive test charge placed at some distance from a charge.
- The electric field due to each charge at that point on the x-axis can be found using the Coulombs formula:
.
- Then one needs to get the x-component of the electric field at the point due to each charge using the concept of the resolution of forces.
- Once the x-components are found, one needs to get the resultant or the algebraic sum of them to calculate the x-component of the total electric field.

Answer:
2. at the lowest point
Explanation:
The motion of the pendulum is a continuous conversion between kinetic energy (KE) and gravitational potential energy (GPE). This is because the mechanical energy of the pendulum, which is sum of KE and GPE, is constant:
E = KE + GPE = const.
Therefore, when KE is maximum, GPE is minimum, and viceversa.
So, the point of the motion where the KE is maximum is where the GPE is minimum: and since the GPE is directly proportional to the heigth of the bob:
we see that GPE is minimum when the bob is at the lowest point,so the correct answer is
2. at the lowest point
The three phases of matter differ in properties just because of the proximity of their molecules. The solid phase is the most organized of all. Its atoms are compactly arranged together and has the strongest intermolecular forces to keep them together. This is why they have a definite shape and volume. The liquid phase have molecules that are far away from each other, but not as far as that of the gas phase. The liquid and gas phases can be lumped into one group called fluids because they have the same property - they take the shape and volume of their container.
