To calculate the unknown quantity A, first we have to understand the relationship between the given quantities L, V, J, S, and A.

The formula relating the magnetic force (F) acting on a current-carrying conductor in a magnetic field is given by:

F = B I L * sin(θ)

where:

B is the magnetic field strength (given as V = 0.8 T)I is the current (given as J = 5 A)L is the length of the conductor (given as L = 0.4 m)θ is the angle between the magnetic field and the current (not given, assuming it is perpendicular, so sin(θ) = 1)F is the force acting on the conductor

The area of the loop (A) can be calculated using the formula:

A = L * S

where:

S is the perpendicular distance between the sides of the loop (given as S = 0.2 m)

Substitute the values into the formula:

A = 0.4 m * 0.2 m
A = 0.08 m^2

Therefore, the area of the loop is 0.08 square meters.
