Answer:
Miller Indices are [2, 4, 3]
Solution:
As per the question:
Lattice Constant, C = 
Intercepts along the three axes:



Now,
Miller Indices gives the vector representation of the atomic plane orientation in the lattice and are found by taking the reciprocal of the intercepts.
Now, for the Miller Indices along the three axes:
a = 
b = 
c = 
To find the Miller indices, we divide a, b and c by reciprocal of lattice constant 'C' respectively:
a' = 
b' = 
c' = 
Explanation:
It is given that, two teams are playing tug of war.
Force applied by Team A, 
Force applied by Team B, 
We need to find the net force acting on the rope. It is equal to :



So, the net force acting on the rope is 35 N and it is acting toward right. Hence, this is the required solution.
A lot of it is all experimental as long as you are taking caution of safety while doing it. I personally would use copper wiring mainly for the fact that it is a nice conductor. For the wrap around the wiring i usually would use black or red electrical tape just because it has very nice insulator properties and is safe to use.
