If the system above is in equilibrium, the tension in the string Q is
-
A.
11N -
B.
9N -
C.
4N -
D.
6N
Correct Answer: Option B
Explanation
If the string is in equilibrium, the the tension in the string Q = 4N + 5N = 9N
If the string is in equilibrium, the the tension in the string Q = 4N + 5N = 9N
