Expert Answer:

You need to draw the free body diagram for this question. R = m(g+a). The value of R will be the reading of the spring balance.

A convenient way to remeber  this point in the exams is when you go up in a lift you feel heavy, so R =m(g+a). when you move downwards you feel ligher and R = m(g-a).
