Answer:
584.3 m at above the positive x-axis
Explanation:
We have to find the magnitude and direction of the resultant vector. In order to do that, we have to resolve each vector along the x- and y- direction first.
Resolving the vector L:
Resolving the vector M:
Now we can find the components of the resultant vector by adding the components of each vector along each direction:
So the magnitude of the resultant vector is
While the direction is given by:
But since is negative and is positive, it means that this angle is measured as angle above the negative x-axis; so the direction of the vector is actually
Okay so yeah u have to minus then subtract then decide it it’s a method i was taught to do
Answer:
Explanation:
Gauss' Law should be applied to find the E-field 3.9 cm from the surface of the sphere.
In order to apply Gauss' Law, an imaginary spherical shell (Gaussian surface) should be placed around the original sphere. The exact position of the shell must be 3.9 cm from the surface of the original sphere.
Gauss' Law states that
Here, the integral in the left-hand side is equal to the area of the imaginary surface. After all, the reason behind choosing the imaginary surface a spherical shell is to avoid this integral. The enclosed charge in the right-hand side is equal to the charge of the sphere, -84.0 nC. The radius of the imaginary surface must be 5 + 3.9 = 8.9 cm.
So,
