Using Newton's second law, F = ma, we can solve for the unknown force:

F = ma - known force
F = 4.0 kg x 11e7ff9_2a7b_9e19_a768_39118c1701d2_TB2295_11 M/s^2 - 11ea7ff9_2a7b_9e1a_a768_0feaa184164f_TB2295_11 N
F = 44 N - 13 N
F = 31 N

Therefore, the magnitude of the other force acting on the object is 31 N, which corresponds to choice B.
