Answer:
The charge is 0.056 nC.
Explanation:
Given that,
Electric field = 2000 N/C
Distance = 5.0 cm
We need to calculate the charge density
Using formula of charge density


Put the value into the formula


We need to calculate the charge in 1.0 cm
Using formula of charge




Hence, The charge is 0.056 nC.
Answer:
my dad is a physics professor so when he comes home i will tell him to answer the question for you
Answer:
Magnetic flux, 
Explanation:
It is given that,
Magnitude of the magnetic field, B = 0.078 T
Radius of circular loop, r = 0.1 m
The field is oriented at an angle of θ = 25° with respect to the normal to the surface. The magnetic flux through the surface is given by :



or

So, the magnitude of magnetic flux through the surface is
. Hence, this is the required solution.
