Two boxes are held together by a strong wire and attached to the ceiling of an elevator by a second wire (see diagram to the left). The mass of the top box is 14.2 kg; the mass of the bottom box is 10.4 kg. Assume that the acceleration due to gravity is 9.8 m/ s^2. Find the tension in the top wire (connecting points A and B)

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

conservation of mass

mass before something happens = mass afterwards

find the sum of the two horizontal vectors and the sum of the two vertical vectors
