Answer:

True!

Step-by-step explanation:

F = ma (force = mass times acceleration)

The force on each skater will be the same because of Newton's 3rd law...

F (1st skater) = F (2nd skater)

ma (1st skater) = ma (2nd skater)

If the skaters have different masses, they WILL have a different acceleration. Feel free to ask questions if needed.
