Answer:
1.336 m
Explanation:
q = - 3.77 micro C at y = 0 m
Q = - 4.92 micro C at y = 2.86176 m
Let the electric field is zero at P which is at a distance y from origin.
Electric field at P due to q is equal to the electric field at P due to Q.
2.86176 - y = 1.142 y
2.142 y = 2.86176
y = 1.336 m
Thus, the electric field is zero at y = 1.336 m.
The resultant of the vectors is .
<h3>What is a resultant vector?</h3>
A resultant vector is the vector sum of two or more vectors.
The given vectors;
- Height of vector A = HA
- Height of vector B = HB
- Height of vector C = HC
The height of vector B is the resultant of the three given vectors.
When the vectors are drawn from head to tail, the vector B forms the resultant of the two other vectors (A and C).
Thus, the resultant of the vectors is .

Explanation:
Mass of a proton,
Mass of an electron,
The distance between the electron and the proton is,
We need to find the mutual attractive gravitational force between the electron and proton. The gravitational force is given by :
Where G is the universal Gravitational constant
So, the force between the electron and proton is .
Answer:
2.5
Explanation:
The capacitance of a parallel-plate capacitor filled with dielectric is given by
where
k is the dielectric constant
is the capacitance of the capacitor without dielectric
In this problem,
is the capacitance of the capacitor in air
is the capacitance with the dielectric inserted
Solving the equation for k, we find
