Calculate the magnitude of the force exerted by each wire on a 1.20-m length of the other.

Zielflug [23.3K]

Incomplete question.The complete question is attached below as screenshot along with figure

Answer:

$F=6.00*10^{-6}N$

Force is repulsive

Explanation:

Given data

Current I₁=5.00A

Current I₂=2.00A

Length L=1.20 m

Radius r=0.400m

To find

Force F

Solution

As the force is repulsive because currents are in opposite direction

From repulsive force we know that:

$F=\frac{u_{o}I_{1}I_{2}L}{2\pi r}$

Substitute the given values

$F=\frac{u_{o}(5.00A)(2.00A)(1.20m)}{2\pi (0.400m)}\\ F=6.00*10^{-6}N$

Two people pull on a horizontal spring that is attached to an immovable wall. Then, they detach it from the wall and pull on opp

zimovet [89]

Answer:In first case

Explanation:

When two People pull the spring, let the applied force by each person be $F_o$

and spring constant of spring be k

so Total force is $2F_o$

total extension according to Hooke's law is

$x=\frac{2F_o}{k}$

When they detach the spring and apply force in opposite direction then force on either side is F so net extension is

$x'=\frac{F_o}{k}$

so in first case there will be more extension
