Answer:
The negative sign represents the flow of charge in an opposite direction relative to point of action.
384,400 in scientific notation can be written as 3.844×10^5
Explanation:
if the elevator is moving upward with the constant speed the spring scale will read 18 N which is the mass of each of the two blocks attached by separate springs to the scale at opposite ends.
Considering the magnetic force is providing the centripetal force,
we get, mv^2/r = qvB
so, r = mv/qB
as the Kinetic energy, K of the particle is given by.5mv^2
so, v = sqrt(2K/m)
substituting the in radius equation,
<span>r = m*sqrt(2K/m)/qB
r = sqrt(2Km)/qB</span>
there are three picture with example and sentence
