homework_02_electric_fields_zero
Two charges are fixed in place on the [x]-axis as shown.
- Let
- [q_0 = -2.0 \mu c] be the red charge on the left.
- [q_1 = 4.0 \mu c] be the blue charge on the right.
- [r = d = 12.0 cm] be the destance be btween the charges.
Find [h] along the [x]-axis such that the electric field is zero.
- [h = -28.9706]
- [0 = k \left(\left(\frac{ q_1}{ h^2}\right) - \left(\frac{ q_2}{ \left(r + h\right)^2\right)\right) ]
- Solve for [-h]
- [0 = k \left(\left(\frac{ q_1}{ h^2}\right) - \left(\frac{ q_2}{ \left(r + h\right)^2\right)\right) ]
