Question

The Young’s modulus of the material of a wire is equal to the

Stress required to increase its length four times
Stress required to produce unit strain
Strain produced in it
Half the strain produced in it

The correct answer is: Stress required to produce unit strain

Young’s modulus of material $Y equals fraction numerator L i n e a r blank s t r e s s over denominator L o n g i t u d i n a l blank s t r a i n end fraction$
If longitudinal strain is equal unity, then
$Y equals$ Linear stress produced

Two magnets of equal mass are joined at 90 $degree$ each other as shown in figure. Magnet $N subscript 1 end subscript S subscript 1 end subscript$ has a magnetic moment $square root of 3$ times that of $N subscript 2 end subscript S subscript 2 end subscript$ . The arrangement is pivoted so that it is free to rotate in horizontal plane. When in equilibrium, what angle should $N subscript 1 end subscript S subscript 1 end subscript$ make with magnetic meridian?
