Can three vectors not lying in a plane give zero resultant?

No, if three vectors do not lie in a plane, they cannot give zero resultant.

Explanation:

Let A, B and C be three vectors. If they give zero resultant, then

A+B+C=0

or, A= -(B+C)

Hence, they will produce zero resultant, if A is equal to negative of vector (B+C). The vector (B+C) lies in the plane of B and C. Hence, A will be equal to negative of (B+C) if A, B and C all lie in a plane.

कमपयुटर परयोग भइरहेको कूनै दुई कषेतरहरूको नाम लेखनुहोस ।
डिजिटल साकषरता भननाले के बुझिनछ ?
सूचना तथा सञचार परविधि भनेको के हो ?
कमपयुटर हारडवेयरलाई उदाहरणसहित वरगीकरण गरनुहोस ।
कमपयुटरको परयोग आज...

4.कमपयुटर हारडवेयर तिन परकारमा विभाजित छ। तिनीहरू हुन :

इनपुट उपकरण ( माउस, किबोरड, सकयानर)

आउटपुट उपकरण ( मनिटर, परिनटर, सपिकर)

परशोधन उपकरण (सि.पी. यु)

सोरेज उपकरण ( सिडि, पेन.डराइभ)

5.धेरै पहिले, कमपयुटरहरू मुखय रूपमा संखयाहरू गणना गरन र शबद परशोधन गरन परयोग गरिनथयो। समय परिवरतन भएसँगै, कमपयूटरले हामीलाई हामरो दैनिक कारयहरूमा मददत गरनको लागि विकसित गरेको छ। आजकल हामी वयकतिगत रमाइलोको लागि आफनो कमपयुटरलाई खेलको लागि परयोग गरेर र इनटरनेटमा जानकारी फेला पारन परयोग गरछौं। हामरो दैनिक जीवनमा कम...

Is it possible that the resultant of two vectors be smaller than the smaller of the two vectors? If so, under what condition?

Yes, if the angle between the two vectors is more than 90^o but less than 270⁰. (cosΘ is negative)
