1. A proton is entering magnetic field B 0.2 i-0.5 j+ 0.4 k. If the proton moves at v (4000i + 5000 k) in meters per second, find the force vector acting on the proton. Proton charge is 1.6 x 10 C a. F = (4000 i + 960 j -3200 k) x 1019 N c. F = (4000 i – 960 j -3200 k) x 10-19 N. b. F = (4000 i - 960 j+3200 k) x 1019 N d. F = (4000 i + 960 j +3200 k) x 10-19 N
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
