The x-component is related with the Force through the trigonometric function cosine.
cos(42°) = x-component / F ⇒ x-component = Fcos(42°) = 112N*0.743 = 83.2 N
Answer:
Explanation:
We shall apply Gauss's theorem to calculate the electric flux through a closed surface due to charge contained in side
Total charge inside surface = zero
So total electric flux through closed surface will be zero.
or electric flux going out = electric flux coming in
(a) The electric field is zero everywhere on the surface. True
(b) The electric field is normal to the surface everywhere on the surface. - false
(c) The electric flux through the surface is zero. True
(d) The electric flux through the surface could be positive or negative - false
(e) The electric flux through a portion of the surface might not be zero - True
It does work or increases thermal energy
