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\!

Can two vectors of an unequal magnitude add up to give a vector with a magnitude of zero?
Mademuasel [1]
Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.
