Answer:
Tension T1 is less than tension T2.
T1 < T2
Explanation:
According to given data,
mass of box A ( mA) is grater than mass of box B (mB)
we can write,
m(A) > m(B)
Newton's second law states that:
Tension of object is directly proportional to the mass of the system.
T ∝ m
here Boxes A and B are being pulled to the right on a frictionless surface,
so Tension T1 generates due to the mass of box A m(A)
and Tension T2 arises due to mass of the system m(A) + m(B)
Thus tension T1 will be less than tension T2
T1 < T2

Answer:
When the plane of the loop is perpendicular to the field lines, the magnetic flux through the loop is 6.284 x 10⁻³ wb.
Explanation:
The magnetic flux through the loop is the product of magnetic field strength, circular area of the loop and angle of inclination.
Ф = BAcosθ
When the plane of the loop is perpendicular to the field lines, θ = 0
Ф = BAcos0
Ф = BA
Where;
Ф is the magnetic flux through the loop
B is the magnetic field strength = 0.8 T
A is the circular area of the loop;
Ф = 0.8 x 0.007855 = 6.284 x 10⁻³ wb
Therefore, when the plane of the loop is perpendicular to the field lines, the magnetic flux through the loop is 6.284 x 10⁻³ wb.
