Question

young modulus of a material of wire is 1.2x10¹¹N/m² Calculate the radius of wireif the load of 8 kg .wt​

Answer 1

Explanation:

Let length of rectangle=lcm

breadth of rectangle= bcm

Given length is 3 times its breadth

i.e. l= 3×b

Perimeter of the rectangle= 120 cm

i.e.2×( l+ b)=120

2×(3×b+ b)=120

2×(4×b)=120

8×b=120

b= 15 cm

SO SORRY DEAR FOR MY WRONG ANSWER BUT YE ZARURI THA
