Problem 3 A wire of length 16cm is suspended by flexible leads above a long straight wire. Equal but opposite currents are estab

oksian1 [2.3K]

Answer:

Option B

Solution:

As per the question:

Length of the suspended wire, l = 16 cm = 0.16 m

Distance between the long wire and the suspended wire, R = 1.5 mm = 0.0015 m

Mass of the 16 cm wire, m = 0.014 kg

Now,

We know that the magnetic field due to the two parallel current carrying straight long wires with current 'I' and the separation 'R' between the wires is given by:

$B = \frac{\mu_{o}I}{2\pi R}$ (1)

If the suspended wire floats, force due to its weight is balanced by the magnetic force due to current I:

mg = IBl

Also, from eqn (1):

mg = $I\frac{\mu_{o}I}{2\pi R}l$

mg = $\frac{\mu_{o}I^{2}l}{2\pi R}$

$0.014\times 9.8 = I\frac{4\pi \times 10^{- 7}I}{2\pi \times 0.0015}\times 0.16$

$I^{2} = 6430.436$

I = 80.19 A

I = 80 A (approx)

How was the water filtered to remove debris and living organisms?

ira [324]

<span>The most common method in removing debris and living organisms is through a series of sedimentation and heat application. The role of sedimentation is to use gravity in separating drinkable water and visible debris. While treating water with heat kills the living organisms.</span>
