Statement I : The minimum number of non-coplanar vectors whose sum can be zero, is four.
Statement II : The resultant of two vectors of unequal magnitude can be zero.

Moderate

A

If both statement I and statement II are true and statement II is the correct explanation of statement I.
B

If both statement I and statement II are true but statement II is not the correct explanation of statement I.
C

If statement I is true but statement II is false.
D

If both statement I and statement II are false.

Solution

The resultant of two vectors of unequal magnitude given by $R = \sqrt{A^{2} + B^{2} + 2 ABcosθ} cannot be zero for any value of θ$
