Answer:
Explanation:
Force Mass * acceleration
F = ma
a = F/m
Sum of force = 16.3N - 15.8N = 0.5N
Mass = 0.62kg
Substitute
a = 0.5/ * 0.62
a = 0.81m/s²
The acceleration of the toy is 0.81m/s²
Answer: ![1.298\times 10^{-5}\ N/m](https://tex.z-dn.net/?f=1.298%5Ctimes%2010%5E%7B-5%7D%5C%20N%2Fm)
Explanation:
Given
Current in the first wire ![I_1=2.2\ A](https://tex.z-dn.net/?f=I_1%3D2.2%5C%20A)
Current in the second wire ![I_2=5.9\ A](https://tex.z-dn.net/?f=I_2%3D5.9%5C%20A)
wires are
apart
Force per unit length between the current-carrying wires is
![\Rightarrow \dfrac{F}{l}=\dfrac{\mu_oI_1I_2}{2\pi r}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7BF%7D%7Bl%7D%3D%5Cdfrac%7B%5Cmu_oI_1I_2%7D%7B2%5Cpi%20r%7D)
Force exerted by the wires is the same
Put the values
![\Rightarrow \frac{F}{l}=f=\dfrac{4\pi \times 10^{-7}\times 2.2\times 5.9}{2\pi \times 0.2}=1.298\times 10^{-5}\ N/m](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7BF%7D%7Bl%7D%3Df%3D%5Cdfrac%7B4%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%5Ctimes%202.2%5Ctimes%205.9%7D%7B2%5Cpi%20%5Ctimes%200.2%7D%3D1.298%5Ctimes%2010%5E%7B-5%7D%5C%20N%2Fm)
This force will be repulsive in nature as the current is flowing opposite
