Answer:
function is discontinuous
and
after 3 hours upto day 24 hours fix charge $10
so there are discontinuous at 1st hour, 2nd hours and 3rd hours
Explanation:
given data
charge = $3 for 1st hour
charge = $2 for each succeeding hour
maximum charge = $10 daily
to find out
Is this function continuous
solution
their function is 3 +2x
so function is discontinuous here
and
this is very clear for 1st hour or part of hour it mean charge a fix value in given time
anyone who park fix charge for 60 min up to the 3 hours
after that for day 24 hours fix charge $10
so there are discontinuous at 1st hour, 2nd hours and 3rd hours
Solution :
As the charge is stationary, hence
Hence, no torque at all.
When the charge is moving in positive x direction and the field will be in the negative y direction outside the bar, then :
Hence, the force have direction .
When instead of charge, an iron nail is used, then there will be induced magnetic field in the soft iron. The nature of the pole induced will be opposite near tot he bar. That is the north pole will be induced near the south pole and vice versa. That is why whichever be the pole of magnet closest to iron will be attracted by iron.
