Find the magnitude of the electric field in the capacitor

AI Thread Summary
To find the magnitude of the electric field in a parallel-plate capacitor, the electric force on the electron must be determined using Newton's second law. The deflection of the electron by 0.594 cm can be analyzed through kinematic equations, similar to projectile motion. The initial speed of the electron is given as 5.20 x 10^-6 m/s, which will also be needed to calculate its final speed upon exiting the capacitor. By applying these principles, the required calculations can be performed to solve for both the electric field strength in N/C and the electron's speed in m/s. Understanding the relationship between electric force, acceleration, and motion is crucial for solving the problem.

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).
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
