A vector A when added to the vector B = 3i + 4j yields a resultant vector that is in the positive y direction and has a magnitude equal to that of B. Find the magnitude of A A vector A when added to the vector B = 3i + 4j yields a resultant vector [...]

Two identical cylindrical vessels, each of base area A, have their bases at the same horizontal level. They contain a liquid of density p. In one vessel the height of liquid is h1 and in the other h2(>h1​). When two vessels are connected, the work done by gravity in equalizing the levels is each of [...]

The resultant of two vectors P and Q is R. If the magnitude of Q is doubled, the new resultant vector becomes perpendicular to P. Then, the magnitude of R is equal to the magnitude of R is equal to the new resultant vector becomes perpendicular to P. Then The resultant of two vectors P [...]
