An iron weight, suspended by a string, is motionless. The tension in the string is 4.75 newtons. What is the mass of the iron weight?
Since weight is motionless, net force is equal to zero.
According to Newton's 2nd law of motion,
T - mg = 0-----------(T = tension, mg = weight of mass)
4.75 = m x 9.8
m = 4.75/9.8
m = 0.48 kg.
Hope this helps\!
