This is the last question I have on my study guide that I cant solve. My physics test is tomorrow and I just want to be ready for it. Please help me figure this one out! What is the gravitation force on mass 1 if each mass is 2 kg? O<---(5m)---->O mass3 I - I - (2m) - I - O - < mass1 Well I hope you can understand that. I know that the hypotonuse is the square root of 29 so im guessing I need to use the formula F=F12+F13 to get the answer right or wrong?
