The figure below shows a plastic ring of radius \( R=50 \mathrm{~cm} \). Two small charged beads are on the ring: Bead 1 of charge \( +2 \mu C \) is fixed in place at the left side; bead 2 of charge \( +6 \mu C \) can be moved along the ring. The two beads produce a net electric field of magnitude \( E \) at the center of the ring. At what positive value of angle \( \theta \) (in degrees) should bead 2 be positioned such that \( E=2 \times 10^{5} N / C ? \) \( \square \)

Step 1
Bead 1 has a charge of \( +2 \, \mu C \) and is fixed at the left side of the ring. Bead 2 has a charge of \( +6 \, \mu C \) and can be moved along the ring. The radius of the ring is \( R = 50 \, \text{cm} = 0.5 \, \text{m} \). Show more…

Plastic Ring Figure $23-33$ shows a plastic ring of radius $R=50.0 \mathrm{~cm}$. Two small charged beads are on the ring: Bead 1 of charge $+2.00 \mu \mathrm{C}$ is fixed in place at the left side; bead 2 of charge $+6.00 \mu \mathrm{C}$ can be moved along the ring. The two beads produce a net electric field of magnitude $E$ at the center of the ring. At what angle $\theta$ should bead 2 be positioned such that $E=2.00 \times 10^{5} \mathrm{~N} / \mathrm{C} ?$
The figure shows a plastic ring of radius R = 50.3 cm. Two small charged beads are on the ring: Bead 1 of charge +2.12 μC is fixed in place at the left side; bead 2 of charge +6.18 μC can be moved along the ring. The two beads produce a net electric field of magnitude E at the center of the ring. At what (a) positive and (b) negative value of angle θ should bead 2 be positioned such that E = 2.06 × 105 N/C?
