When a vector $\overrightarrow{A}$$=-2\hat{i}+4\hat{j}+7\hat{k}$ is multiplied with a scalar 'n' , then the resultant vector $4\hat{i}-8\hat{j}-14\hat{k}.$ Then the value of ‘n’, is

Solution:

When a vector $\overrightarrow{A}$$=-2\hat{i}+4\hat{j}+7\hat{k}$ is multiplied with a scalar 'n' , then the resultant vector $4\hat{i}-8\hat{j}-14\hat{k}.$ Then the value of ‘n’ is −2
