Final answer:
When neither team is moving in a tug-of-war, the net force on each team is zero due to the balanced forces exerted by both teams.
Step-by-step explanation:
The net force on the left team during a tug-of-war when neither team is moving is zero. This is because the forces from both teams are balanced, resulting in no net motion. If each member of the first team exerts a horizontal force of 1350 N, and each member of the second team exerts 1365 N, the net force on the left team would be the sum of their forces subtracted by the sum of the right team's forces. However, since the question states the match has been even so far, we can assume that the forces are exactly balanced, leading to a net force of zero on both teams.
