Answer:
923.44N
Explanation:
Obviously Fn cannot equal Fg since the elevator is moving up  
Where Fn is the force read on the scale
 Fg is gravitational force=mg=77.6 x 9.8=760.48N
So we use this equation:  
Fnet = Fn - Fg  
ma = Fn - mg
77.6 x 2.1 = Fn – 760.48
162.96N = Fn – 760.48N  
923.44 N = Fn
The answer is 923.44 N
