a. Two foeces are added using triangle rule because force is a vector quantity.
Force is a vector quantity because two forces are added using triangle rule.

Two physical quantities of which one is a vector and the other is a scalar having the same dimensional formula are :

Which of the following statements is/are correct. Statement-(i) The electric field strength decreases. Statement-(ii) The electro force of attraction betweeen the plates increases. Statements-(iii) The potential difference between the plates increases.

At what angle should the two forces vectors 2F and sqrt(2) F act so that the resultant force is sqrt(10)F

The four pairs of force vectors are given, which pairs of force vectors cannot be added to give a resultant vector of magnitude 10N ?

The vector sum of two forces is perpendicular to their vector differences. In that case, the force
