Question

which pair of following forces will never give resultant force of 2n? a) 2n and 2n, b) 1n and 1n, c) 1n and 3n, d) 1n and 4n​

Answer 1

The triplet (1N.4N2N) can't form a triangle since 2+1<4 the triangle inequality sates that the sum of any two sides in a triangle must be greater than the third side

So, the (1N,4N) vector pair can't form a 2N resultant vector.
Hence , Option D is the correct answer.
