The classical physics works on the Newton's laws of motion. It is applicable on heavenly bodies which are governed by the gravitational force. On the other hand, Quantum Physics is applicable for very low mass and sized bodies like electron, protons etc. The classical physics would accurately describe the motion of satellite moving with speed 7500 m/s using the following formula:
where G is the gravitational constant, M is the mass of the planet and v is the orbital speed. Then radius of the orbit can be described by this formula.
The proton's electrostatic force exerted on the electron will be 3.5×10¹² N.
<h3>What is the electrostatic force?</h3>It is a force imposed by one charge on another as a result of the field.
The electrostatic force produced by one line charge on another line charge separated by r is determined by the charge potency of each charge as well as the separation distance between them.
The electrostatic force is found as:
Hence, the proton's electrostatic force exerted on the electron will be 3.5×10¹² N.

Answer:
T1 = T2 = 602.33 N
Explanation:
I attached an image of the forces diagram below.
The x component of the forces for this cases is:
And the y components:
The angle is calculated by using the information about the length of the cable and the vertical distance of the traffic light:
Thus, you obtain:
hence, the tension in both segments of the cable is 602.33 N
