Answer:
A
Explanation:
The net force on an object is positive if it is moving to the right:
ΣF > 0
where, in this case, the forces to the right are positive, and the forces to the left are negative.
Calculating the forces for each answer choice:
A. ΣF = 8N - 6N
= 2N > 0 (positive)
B. ΣF = 8N - 10N
= -2N < 0 (negative)
C. ΣF = 10N - 10N
= 0N (no force)
D. ΣF = 8N - 13N
= -5N < 0 (negative)
So, the toy is likely to accelerate with the applied forces diagrammed by answer option A.
