Velocity is a vector quantity which has both magnitude and direction. ... Net force is also a vector quantity which has both mag
2 answers:
The gravitational force represents the net force on an object traveling in an elliptical trajectory. The force vector consistently directs towards the object being orbited by the moving object. In the sun and earth scenario, this vector continually points toward the sun
The exact strength of this force can be calculated using Newton's universal gravitation law. The formula to determine this force's magnitude is
In this equation signifies the universal gravitational constant,
denotes the distance between both objects, and
represents the masses of the main object and the orbiting body. Thus, it can be inferred that the force magnitude is greater when closer to the central object compared to when farther away.

1) The electric potential energy can be defined as the product of the electric potential and the associated charge:
where
q refers to the charge
V denotes the electric potential
In this scenario, the charge on the rod is
, and the potential energy is 
, thus we may rearrange the earlier formula to find the electric potential at the tip:
2) Using this same formula, if the charge changes to
, the resulting electric potential will be:
where
q refers to the charge
V denotes the electric potential
In this scenario, the charge on the rod is
2) Using this same formula, if the charge changes to
Explanation:
The initial time is t₁ = 2:30 pm
The final time is t₂ = 2:30:45
We must analyze the students' motion concerning time. The final time exceeds the initial time by 45 seconds.
Change in time,
Therefore, this is the solution we need.
