What is the value of resultant vector of two vector with equal magnitude ....pls answer the question with defination

Answer»

As VECTOR is a directed quantity, therefore, its addition DEPENDS UPON the DIRECTION of the vectors to be added. Hence, it is possible that the resultant of two vectors of equal magnitudes yield a vector of the same MAGNITUDE provided we look for an appropriate angle between the two vectors..

Write the condition when the net force of a body is not zero​

Answer»

Hope it helps u✌✌Explanation:Net Force Must Be ZeroThe net force acting on the OBJECT must be zero. Therefore all forces BALANCE in each direction. For EXAMPLE, a car moving along a highway at a constant speed is in equilibrium, as it is not accelerating in any FORWARD or vertical direction. Mathematically, this is stated as Fnet = ma = 0.

What does the pith ball experiment demonstrate ?​

Answer»

tion:A pith ball is a very small, LIGHTWEIGHT object that picks up electric CHARGE quite well. A charged pith ball works well to show the Coulomb force between two charged OBJECTS. If a glass ROD is rubbed with SILK, the silk rubs some electrons off the rod. The rod thus becomes positively charged.
