Box A has a mass of 35.0kg and Box B has a mass of 20.0kg. What is the tension on Box B if the acceleration of the system is -2.67m/s2 clockwise?

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

c) up is the direction the magnetic force is acting on the charge.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
