In the diagram, 91, 92, and q3 are in a straight line. Each of these particles has a charge of
-2.35 x 10-6 C. Particles qı and q2 are separated
by 0.100 m and particles q2 and q3 are separated
by 0.100 m. What is the net force on particle q3?
Remember: Negative forces (-F) will point Left
Positive forces (+F) will point Right

hypothesising or postulating

the force on the thing and the distance the force moves the thing

so easy. just google the electromagnetic waves and it’ll pop up.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
