Question

If there are 11 vectors each pand if each side of polygon subtends an angle30 degrees at
the centre of the polygon. Then the resultant is
CHALLENGE ACCEPTED​

Answer 1

Answer:

12 vectors at 30° can make resultant

$\vec{0}$

due to circular symmetry

vector sum of 11vector + 12vector = 0

${ \sf{R + \vec{p}}} = 0 \\ { \sf{R = - \vec{p}}}$

Hence resultant vector will be opposite direction of R

${ \sf{ - R = - ( - \vec{p})}} \\ \: \: \: \: \: \: \: \: \: \: = \vec{p}$

so, option a is your answer
