Force of 500 N is acting on the parachutist.
Parachutist applies 500 N force in downward direction.
Answer:
300 N upward
Solution:
Parachutist feels air resistance of 800 N.
Thus, 800 N of force is acting in upward direction.
Total force acting on the parachutist is given by,
= air resistance force - force of parachutist
= 800-500
= 300 N
Direction of force is in upward direction because the air resistance force is more than force of parachutist.

Explanation:
The area of the circular loop is given by:
The magnetic flux is given by:
is parallel to
and
is constant in magnitude and direction therefore:
Part A)
initially the flux is
after the interval
the flux is
now, the EMF is defined as:
,
if we consider very small then we can re-write it as:
then:
Part B)
When looked down from above, the current flows counter clockwise, according to the right hand rule, if you place your thumb upwards (the direction of the magnetic field) and close your fingers, then the current will flow in the direction of your fingers.
