Answer:
Resultant force, R = 10 N
Explanation:
It is given that,
Force acting along +x direction, ![F_x=8\ N](https://tex.z-dn.net/?f=F_x%3D8%5C%20N)
Force acting along +y direction, ![F_y=6\ N](https://tex.z-dn.net/?f=F_y%3D6%5C%20N)
Both the forces are acting on a point object located at the origin. Let the resultant force of the object is given by R. So,
![R=\sqrt{F_x^2+F_y^2+F_xF_y\ cos\theta}](https://tex.z-dn.net/?f=R%3D%5Csqrt%7BF_x%5E2%2BF_y%5E2%2BF_xF_y%5C%20cos%5Ctheta%7D)
Here ![\theta=90^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D90%5E%7B%5Ccirc%7D)
![R=\sqrt{F_x^2+F_y^2}](https://tex.z-dn.net/?f=R%3D%5Csqrt%7BF_x%5E2%2BF_y%5E2%7D)
![R=\sqrt{8^2+6^2}](https://tex.z-dn.net/?f=R%3D%5Csqrt%7B8%5E2%2B6%5E2%7D)
R = 10 N
So, the resultant force on the object is 10 N. Hence, this is the required solution.
Answer:
(a) ε = 1373.8.
(b) The wingtip which is at higher potential.
Explanation:
(a) Finding the potential difference between the airplane wingtips.
Given the parameters
wingspan of the plane is = 18.0m
speed of the plane in north direction is = 70.0m/s
magnetic field of the earth is = 1.20μT
The potential difference is given as:
ε = Blv
where ε = potential difference of wingtips
B = magnetic field of earth
l = wingspan of airplane
v = speed of airplane
ε = 1.2 x 18.0 x 63.6
ε = 1373.8
(b) Which wingtip is at higher potential?
The wingtip which is at higher potential.
