Answer:
DOWN
Explanation:
When a positive charge is placed in uniform or nonuniform electric field then due to the Electric field present in that region the charge will experience electrostatic force on itself.
This electrostatic force is given as
here we know
q = charge
E = electric field
Now if charge is positive then force on the charge is always in the direction of electric field but if charge is negative then force is exactly opposite to electric field direction.
So here it will have force in the direction of electric field which is DOWN
Answer:
The electric flux is
Explanation:
Given:
The flux of the Electric Field E due to the are dA in space can be found out by using Gauss Law which is as follows
where
Now according to question we have
Hence the electric flux is calculated.
Answer:
Angular velocity is same as frequency of oscillation in this case.
ω = x
Explanation:
- write the equation F(r) = -K with angular momentum <em>L</em>
- Get the necessary centripetal acceleration with radius r₀ and make r₀ the subject.
- Write the energy of the orbit in relative to r = 0, and solve for "E".
- Find the second derivative of effective potential to calculate the frequency of small radial oscillations. This is the effective spring constant.
- Solve for effective potential
- ω = x
