The answer is wrong the correct answer is 20 N
°Vertical component for one string = TsinO
since they are two string the total upward force will be =2×TsinO
2×Tsin30=20 N
so T=20N
The app's marked answer of 40.0 N is a common error found in some test banks. It happens if you forget that there are two strings sharing the load. If you only had one string pulling at 30° to support 20N, then T would indeed be 40N. But with two strings, the workload is split in half.



my school pls ur answer 40N is very wrong, the correct answer is 20N
