JEE Main 5 April 2024, Shift 1, Physics Q53

Question 53 of 90 in this shift, Physics question 23 of 30, Section B.

The density and breaking stress of a wire are

6\times10^{4}\ \mathrm{kg/m^3}

and

1.2\times10^{8}\ \mathrm{N/m^2}

respectively. The wire is suspended from a rigid support on a planet where acceleration due to gravity is

\frac{1}{3}^{\mathrm{rd}}

of the value on the surface of earth. The maximum length of the wire with breaking is ________ m (take,

g=10\ \mathrm{m/s^2}

Official answer
