Which is the best example of a force counteracting fp? using a dolly to push a box to another location two children pulling apart a wishbone a group of dogs pulling a dogsled across ice two people pushing a broken-down car up the road

Option 2 is correct.

Step-By-Step Explanation:

We should know the meaning of counteract  which means to nullify something

Force counteracting is the opposite direction of the force means the force that is applied neutralizes by the counteracting force.

Option 1 is not correct because pushing a box is in 1 direction nothing is opposing the force

Similarly, as option 1 option 3 and 4 are discarded.

Option 2 is correct since,  two children are pulling the wishbone from direction which leads to neutralization of the force.

Therefore, option 2 is correct.
