The horizontal rope is under 7,019.4 N of tension.
The pulling force conveyed axially by a string, cable, chain, or another similar device, or by the ends of a rod, is referred to as tension.
The action-reaction pair of forces acting at the ends of the element can also be referred to as tension.
The tension unit is the Newton.
the horizontal rope is tense.
The following formula is used to determine the horizontal rope's tension:
Apply the torque principle;
Mg (L/2) sin + mg L sin = T(L/2) cos
M + 2mg sin/cos = T
(M + 2m)g tan = T
let θ = 66⁰ (The question should include this value)
(M + 2m)g tan = T
T = (74.9 + 2 x 122)(9.8) (tan 66)
T = 7,019.4 N
7,019.4 N is the tension in the horizontal rope.

Explanation:
B = Magnetic field
v = Velocity of electron = 
q = Charge of electron = 
= Vacuum permeability = 
r = Radius of circle = 0.026 m
N = Number of turns = 103 turns/cm = 
I = Current
The magnetic and centripetal force will be balanced
The magnetic field in solenoid is given by
From the first equation
The current in the solenoid is 0.23348 A

Answer:
To calculate anything - speed, acceleration, all that - we need <em>data</em>. The more data we have, and the more accurate that data is, the more accurate our calculations will be. To collect that data, we need to <em>measure </em>it somehow. To measure anything, we need tools and a method. Speed is a measure of distance over time, so we'll need tools for measuring <em>time </em>and <em>distance</em>, and a method for measuring each.
Conveniently, the lamp posts in this problem are equally spaced, and we can treat that spacing as our measuring stick. To measure speed, we'll need to bring time in somehow too, and that's where the stopwatch comes in. A good method might go like this:
- Press start on the stopwatch right as you pass a lamp post
- Each time you pass another lamp post, press the lap button on the stopwatch
- Press stop after however many lamp posts you'd like, making sure to hit stop right as you pass the last lamp post
- Record your data
- Calculate the time intervals for passing each lamp post using the lap data
- Calculate the average of all those invervals and divide by 40 m - this will give you an approximate average speed
Of course, you'll never find an *exact* amount, but the more data points you have, the better your approximation will become.
