Answer:
13.478 × 10⁻⁵T
Explanation:
Given that,
magnetic field at r = 3cm
due to the current passing through the centre of the hollow cylinder
![B_1 = \frac{U_0I_1}{2\pi r}](https://tex.z-dn.net/?f=B_1%20%3D%20%5Cfrac%7BU_0I_1%7D%7B2%5Cpi%20r%7D)
![B_1 = 2.0 \times 10^-^7 \times \frac{32.0}{3.00 \times 10^-^2} \\\\= 21.33 \times 10^-^5T](https://tex.z-dn.net/?f=B_1%20%3D%202.0%20%5Ctimes%2010%5E-%5E7%20%5Ctimes%20%5Cfrac%7B32.0%7D%7B3.00%20%5Ctimes%2010%5E-%5E2%7D%20%5C%5C%5C%5C%3D%2021.33%20%5Ctimes%2010%5E-%5E5T)
magnetic field at r = 3cm
due to the current passing through the centre of the hollow cylinder
![B_2 = \frac{U_0I_2}{2\pi r}](https://tex.z-dn.net/?f=B_2%20%3D%20%5Cfrac%7BU_0I_2%7D%7B2%5Cpi%20r%7D)
I₂ = current through the hollow cylinder within r₁ = 1.50cm to r₂ = 3.00cm
![I_2 = \frac{24}{\pi (4^2 - 1.5^2)} \times \pi (3^2 - 1.5^2)](https://tex.z-dn.net/?f=I_2%20%3D%20%5Cfrac%7B24%7D%7B%5Cpi%20%284%5E2%20-%201.5%5E2%29%7D%20%5Ctimes%20%5Cpi%20%283%5E2%20-%201.5%5E2%29)
![I_2 = \frac{24 \times 6.75 }{13.75} = 11.782A](https://tex.z-dn.net/?f=I_2%20%3D%20%5Cfrac%7B24%20%5Ctimes%206.75%20%7D%7B13.75%7D%20%3D%2011.782A)
so,
![B_2 = \frac{2 \times 10^-^7 \times 11.782}{3\times 10^-^2} \\\\= 7.855 \times 10^-^5\\](https://tex.z-dn.net/?f=B_2%20%3D%20%5Cfrac%7B2%20%5Ctimes%2010%5E-%5E7%20%5Ctimes%2011.782%7D%7B3%5Ctimes%2010%5E-%5E2%7D%20%5C%5C%5C%5C%3D%207.855%20%5Ctimes%2010%5E-%5E5%5C%5C)
So , magnetic of netfield is
= B₂ - B₁
= 13.478 × 10⁻⁵T
The magnitude of the average force that the ball exerts against his glove is 600 N

<h3>Further explanation</h3>
Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.
![\boxed {F = ma }](https://tex.z-dn.net/?f=%5Cboxed%20%7BF%20%3D%20ma%20%7D)
F = Force ( Newton )
m = Object's Mass ( kg )
a = Acceleration ( m )
Let us now tackle the problem !
![\texttt{ }](https://tex.z-dn.net/?f=%5Ctexttt%7B%20%7D)
<u>Given:</u>
mass of ball = m = 0.15 kg
initial speed of ball = u = 40 m/s
final speed of ball = v = 0 m/s
distance = d = 20 cm = 0.2 m
<u>Asked:</u>
average force = F = ?
<u>Solution:</u>
<em>We will use </em><em>Newton's Law of Motion</em><em> to solve this problem as follows:</em>
![F = m a](https://tex.z-dn.net/?f=F%20%3D%20m%20a)
![F = m (\frac { u^2 - v^2 } { 2d } )](https://tex.z-dn.net/?f=F%20%3D%20m%20%28%5Cfrac%20%7B%20u%5E2%20-%20v%5E2%20%7D%20%7B%202d%20%7D%20%29)
![F = 0.15 \times \frac { 40^2 - 0^2 } { 2 \times 0.2 }](https://tex.z-dn.net/?f=F%20%3D%200.15%20%5Ctimes%20%5Cfrac%20%7B%2040%5E2%20-%200%5E2%20%7D%20%7B%202%20%5Ctimes%200.2%20%7D)
![F = 0.15 \times \frac { 1600 } { 0.4 }](https://tex.z-dn.net/?f=F%20%3D%200.15%20%5Ctimes%20%5Cfrac%20%7B%201600%20%7D%20%7B%200.4%20%7D)
![F = 0.15 \times 4000](https://tex.z-dn.net/?f=F%20%3D%200.15%20%5Ctimes%204000)
![\boxed {F = 600 \texttt{ N}}](https://tex.z-dn.net/?f=%5Cboxed%20%7BF%20%3D%20600%20%5Ctexttt%7B%20N%7D%7D)
