Answer:
Explanation:
When the object fall from the top floor it moves with parabolic motion.
This particular case is a horizontal motion of a projectile, so the equation that relates the distance and the time in the y-axes is:
Here: y is the final height, it will be 0, because the object touch the ground.
y₀ is the initial height, it will be h and v₀ in y-axis is zero, because it has a horizontal initial velocity.
So we have:
(1)
We know that the velocity at the x-axes remains constant, then we have:
x is the distance from the base of the building
we can solve it for t and put on (1).
Solving it for x we will have:
But

Answer:
T₂ = 2482.34 N
Explanation:
Equations of balance of forces
Look at the force diagram in the attached graph:
∑Fx=0
T₂cos α -T₁senα = 0 Equation (1)
∑Fy=0
T₁cos α +T₂sinα-W =0 Equation(2)
Data
m=539 kg
g= 9.8 m/s²
W= m*g= 539 kg* 9.8 m/s²= 5282.2 N
T₁ = 1.88T₂
Problem development
in the equation (1)
T₂cos α-(1.88T₂)senα = 0 We divided the equation by ( T₂cos α)
1 - (1.88)tanα = 0
tanα= 1/(1.88)
tanα= 0.5319
α = 28°
T₂=(1.88T₂)tanα
in the equation (2)
(1.88T₂)cos α+ T₂sinα - 5282.2 =0 We divided the equation by cos α
1.88T₂+ T₂tanα - 5282.2/cos α =0
1.88T₂+ T₂tan(28°) - 5282.2/(cos 28°) =0
1.88T₂+ (0.53)T₂- 5982.46 =0
(2.41)T₂ = 5982.46
T₂ = 5982.46/(2.41)
T₂ = 2482.34 N

Electric force varies directly with the magnitude of each charge, and inversely with the distance between the charges.
but for short....
electrical force depends on the charge and distance
