In the figure, a proton is projected horizontally midway between two parallel plates that are separated by The electrical field due to the plates has magnitude
between the plates away from the edges. If the plates are
long, find the minimum speed of the proton if it just misses the lower plate as it emerges from the field. (e = 1.60 × 10-19 C,
ε0 = 8.85 × 10-12 C2/N ∙ m2, mel = 9.11 × 10-31 kg)
Square Inch
A unit of area measurement equivalent to the area of a square with sides of one inch in length, commonly used in manufacturing and engineering.
Pushing Effort
The force applied to an object in order to move it in a specific direction, often measured to assess efficiency in mechanical systems.
Pulling Effort
The force required to move or tow something, often measured to ensure the adequacy of a vehicle's towing capacity.
Force
Push or pull effort measured in units of weight. Force represents the ability to do work but this ability does not necessarily result in any work done; for instance, you can push all you like on a tractor/trailer combination but it is unlikely to move the vehicle. The formula for force (F) is calculated by multiplying pressure (P) by the area (A) it acts on. F=P*A.
