Answer:

The radius of the loop is 4.94\times10^{5}\ m

Explanation:

Given that,

Current = 0.2kA = 200 A

Number of turns = 35

Magnetic field = 8.9 nT

We need to calculate the radius of one loop

Using formula of magnetic field

B=\dfrac{N\mu_{0}I}{2r}

r=\dfrac{N\mu_{0}I}{2B}

Where, I = current

N = number of turns

B = magnetic field

r = radius

Put the value into the formula

r=\dfrac{35\times4\pi\times10^{-7}\times200}{2\times8.9\times10^{-9}}

r =494183.11\ m

r=4.94\times10^{5}\ m

Hence, The radius of the loop is 4.94\times10^{5}\ m

Consider two conducting spheres with one having a larger radius than the other. Both spheres carry the same amount of excess cha
RSB [31]

Answer: Option (a) is the correct answer.

Explanation:

It is known that potential energy is the energy occupied by an object or substance due to its position is known as potential energy.

Therefore, more is the space occupied by an object more will be its position at a particular location. Hence, more will be its potential energy. On the other hand, smaller is the space occupied by an object, smaller will be the position holded by it.

Hence, smaller will be its potential energy.

Thus, we can conclude that for the given situation the statement, potential energy of the larger sphere is greater than that of the smaller sphere, is true.
