1.	Can the sum of three vectors, i.e.,their resultant, be equal to zero ? Explain.
Answer» Solution :Yes, if the resultant of any TWO of the vectors is EQUAL andoppositeto the THIRD one , the resultant of the three vectors will be zero. Let `VECA,vecb,VECC` bethree vectors related as `veca+vecb=-vecc`.Then `veca+vecb+vecc=0`
