Can we add a displacement vector of 20 m to a displacement vector of 30 m. Expalin .

Text Solution

Verified by Experts

No, we cannot add displacement vector of 20 m to displacement vector of 30 m because displacement is a vector quantity.
As the direction of displacement is not known to us and the angle between two displacement vectors is also unkown , we cannot add these vectors.

There are two vectors Force vec(A) = (hat(i) + 3 hat(j) - hat(k)) N and Position vec(B) = (hat(i) + 3 hat(j) - hat(k))m that can be used by two students Alia and Varun. Following are the steps following by each of them. Alia : Step 1 : Calculate unit vector of vec(A) by dividing it by its magnitude and get hat(A) = (hat(i) + 3 hat(j) - hat(k))/(sqrt11) Alia : Step 2 : Get a displacement vector of magnitude 10m using hat(A) Displacement vector = (10(hat(i) +3 hat(j) - hat(k))/(sqrt11)) m Varun : Step 1 : Calculate unit vector of vec(B) by dividing vec(B) by its magnitude and get, hat(B) = ((hat(i) + 3 hat(j) - hat(k))/(sqrt11)) Varun : Step 2 : Get a force vector of magnitude 10 N by using vec(B) Force vector = (10(hat(i) + 3 hat(j) - hat(k)) N)/(sqrt11) Siddharth, a third student, comes and says when we divide or multiply a vector by a scalar, then the physical quantity represented by the vector from a displacement vector from a force vector or a force vector from a displacement vector as calculated by Alia and Varun repectivley.
