By applying Newton's second law of motion;
ma = mg - T
Where,
m = mass; a = downward accelerations (+ve value) or upward acceleration (-ve value); g = gravitational acceleration; T = tension.
For the current case, the velocity is constant therefore,
a = 0
Then,
0 = mg - T
T = mg = 115*9.81 = 1128.15 N
Tension in the cable is 1128.15 N.

Answer:
a)
b)
c)
d)
e)
Explanation:
Given that
d = 2 cm
V = 200 V

We know that
F = E q
F = m a
E = V/d
So
m a = q .V/d b
---------1
The mass of electron

The charge on electron

Now by putting the all values in equation 1


We know that
a)
s = 0.1 cm


b)
s = 0.5 cm


c)
s = 1 cm


d)
s = 1.5 cm


e)
s = 2 cm


A) 
The magnitude of the capacitive reactance is given by

where
is the angular frequency
C is the capacitance
While the magnitude of the inductive capacitance is given by

where L is the inductance.
Since we want the two reactances to be equal, we have

So we find

B) 7449 rad/s
In this case, we have
is the inductance
is the capacitance
Therefore, substituting in the formula for the angular frequency, we find

C) 
Now we can us the formulas of the reactances written in part A). We have:
- Capacitive reactance:

- Inductive reactance:
