UPSEE Solved Model Paper 4

By basic definitions of scale & vector quantities,
(i) we can add two vectors
(ii) adding a scaler and vector is not possible . we can only either add scaler and scaler or vector and vector
(iii)we can multiply a scaler with a vector this will only its magnitude.
(iv) multplication of two scalars is allowed as this is like multiplying two numbers.
(v) same as part (i)
(iv) a component of vector of a vector is also a vector quantity so we can add a vector with a vector
so (i) , (iii) , (iv) , (v), (vi) are correct.
