JEE Main 2 April 2025, Shift 2, Physics Q29

Question 29 of 75 in this shift, Physics question 4 of 25, Section A.

A body of mass 1 kg is suspended with the help of two strings making angles as shown in figure. Magnitudes of tensions T1T_1 and T2T_2, respectively, are (in N) : (Take acceleration due to gravity 10 m/s210\ \mathrm{m/s^2})

The figure, in words

A block of weight mg hangs from two strings attached to the ceiling: string T1 goes up to the left making 60 degrees with the horizontal, string T2 goes up to the right making 30 degrees with the horizontal.
