Answer:

Explanation:
To calculate the force we need to use this equation

where L is the total length of the wire
So in this case the small element of current is

Because x is the direction of the current flow.
As is said in the problem B is such that
![\vec{B} = B \hat{j} = 0.62\hat{j} [ T]](https://tex.z-dn.net/?f=%20%5Cvec%7BB%7D%20%3D%20B%20%5Chat%7Bj%7D%20%3D%200.62%5Chat%7Bj%7D%20%5B%20T%5D)
so to use the equation above we first calculate the following cross product:

so the force:
So here we use the fact that B=0 in any point of the x axis that is not
, that means that we only need to do the integration between a very short distant behind the point
and a very short distant after that point, meaning:

so is the same as evaluating
at 
that is:

Answer:
a. 5.23 m/s² b. 44.23 N
Explanation:
a. What is the centripetal acceleration of the hammer?
The centripetal acceleration a = rω² where r = radius of circle and ω = angular speed.
Now r = length of chain = 1.4 m and ω = 0.595 rev/s = 0.595 × 2π/s = 3.74 rad/s.
So a = rω²
= 1.4 m × (3.74 rad/s)²
= 5.23 m/s²
b. What is the tension in the chain?
The tension in the chain, T = ma where m = mass of hammer = 8.45 kg and a = centripetal acceleration of hammer = 5.23 m/s². This tension is the centripetal force on the hammer.
So, T = 8.45 kg × 5.23 m/s²
= 44.23 N
The factor that causes that is gravity
