[Rasher]

can some one explain me breifly what is triangle law of vectors and pricipal of homogenity and is parallox caused by a candidate is random error or systematic error ??!!!!! :roll:

 

[beacon_of_light]

Triangle Law of vector means that if the vector arrows form a closed polygon then the body is said to be in equilibrium ...

An equation is homogenous if all the quantities have same base units ...eg M = FM + AI then quantities FM and AI must have same base units as M ...
Parallax errors are random errors... for more info on ERRORS ... follow the link below ...
