Fifteen vectors, each of magnitude 5 units, are represented by the sides of a closed polygon, all taken in same order. What will be their resultant ?

Assertion: The minimum number of vectors of unequal magnitude required to produce zero resultant is three. Reason: Three vectors of unequal magnitude which can be represented by the three sides of a triangle taken in order, produce zero resultant.

Prove that when the sides of a triagle are taken in order, it leads to zero resultant.

If a,b,c be the vectors represented by the sides of a triangle taken in order,then a+b+c=0

Three forcesstart acting simultaneously on a particle moving with a velocity overset rarr v . These forces are represented in magnitude and direction by three sides of a triangle taken in the same order. What now will be the velocity of the particle ?

If veca, vecb and vecc are represented by three sides of equilateral triangle taken in same order. P.T. veca+vecb+vec c=vec0 .

three vectors each of magnitude 1N acts along the sides AB,BC,CD of regular hexagon ABCDEF as shown in figure.find the magnitude of their resultant.

The direction of three forces 1N, 2N and 3N acting at a point,are parallel to the sides of an equilateral triangle taken in order. The magnitude of their resultant is:

The maximum and minimum magnitude of the resultant of two given vectors are 17 units and 7 units respectively. If these two vectors are at right angles to each other, the magnitude of their resultant is
