Find the magnitude of the electric field in the capacitor

Click For Summary
SUMMARY

The discussion focuses on calculating the magnitude of the electric field in a parallel-plate capacitor, given an electron's initial speed of 5.20 x 10^-6 m/s and a downward deflection of 0.594 cm. To find the electric field strength (E), the relationship between electric force and acceleration is applied, utilizing Newton's second law and kinematic equations. The solution involves determining the force acting on the electron due to the electric field and subsequently calculating the electric field strength in N/C.

What's the electric force on a charge in an electric field? Apply this to Newton's second law.

Then think about your kinematic equations (like in projectile motion).
