Two vectors having equal magnitudes A make an angle theta with eahc other. Find the magnitude and direction of the resultant.

A charged particle is whirled in a horizontal circle on a frictionless table by attaching it to a string fixed at one end. If a magnetic field is switched on in the vertical direction, the tension in the string

A particle or mass m is moving with speed u in a direction in a which makes 60^(@) with respect to x axis to x axis . It undergoes elastic collision with the well . What is the change in momentum in x and y direction?

A steel tube of length 1.00 m is struck at one end. A person with his ear close to the other end hears the sound of the blow twice one travelling through the body of the tube and the other through the air in the tube. Find the time gap between the two hearings.

Consider a magnetic dipole which on switching ON external magnetic field orient only in two possible was i.e., one along the direction of the magnetic field (parallel to the field ) and another anti-parallel to magnetic field. Compute the energy for the possible orientation . Sketch the graph.

A stone tied to the end of a string 80 cm long is whirled in a horizontal circle with a constant speed. If the stone makes 14 revolutions in 25 seconds, what is the magnitude and direction of acceleration of the stone?

The distance between one end and the other end is called____.
