Three blocks `A,B and C` of masses `4kg,2 kg and 1 kg` respectively, are in contact on a frictionless surface, as shown in the figure. If a force of `14N` applied on the 4 kg block, then the contact force between A and B is
Vectors are the physical quantities which have both magnitudes and directions and obey the triangle/parallelogram laws of addition and subtraction. It is specified by giving its magnitude by a number and its direction, e.g. Displacement, acceleration, velocity, momentum, force, etc. A vector is represented by a bold face type and also by an arrow placed over a letter, i.e. `F, a, b` or `vecF,veca,vecb`.The length of the line gives the magnitude and the arrowhead gives the direction.The point P is called head or terminal point and point 0 is called tail or initial point of the vector OP.Amongst the following
