I have many doubts from this book.
But it's over rite? U could have cleared in FIITJEE.
In the search box, please type " three equal weights of mass" to get to the question
if u have doubts post question by question in some group
Ok, no problem. The question is based on tension in the string. Can you please explain what it is?
|dw:1329839237758:dw|
Three equal weights of mass 2 kg each are hanging on a string passing over a fixed pulley as shown in the figure. The tension in the string connecting the weight B and C is
4 * 10 = 40N? Is it correct?
Answer given is 13N
But how to proceed? I am getting confused.
Can anyone help please?
i will get back to this it wud be nice if u post thsi as a question in physics group clearly with the diagram
|dw:1329929565452:dw| what i have done aBOVE is FREE-BODY DIAGRAM showing all forces acting on the bodies T-mg=ma mg+t-T=ma mg-t=ma solve for 3 unknown now how to determine the forces acting on a body? clue 1: all are accelearting with same'a' 2: look for the immediate bodies in contact with the body u are drawing for 3:TENSION ALWAYS PULLS 4:put urself in the position of the weights and see who is pulling u where?
