2. What is the force existing between two spheres of mass 10 kg each and placed 100 cm apart? Solution: m 1 = m 2 = 10 kg Distance d =100 cm G=6.6734 x 10 - 1 1 Nm 2 /kg 2 ..

An infinite number of charges each equal to 'q' are placed along with X-axis at x = 1m, x = 2m, x = 4m, x = 8m, and so on. Find the electric potential at the point x = 0 due to this set of charge..

1) Find the length of a simple pendulum whose time period is 6.28 s. Time period T = 6.28 s. Length of the pendulum = 9.8 m 2) Time taken by a simple pendulum to execute 20 oscillations is 28 s. What is the time period? Time taken to execute 20 oscillations = 28 ..

Torque in Two and Three Dimensions - If a force acts on a particle P, then the torque acting on the particle with respect to the origin O is given by where gives the position of the particle with reference to the origin O. If both and lie in the XY plane the..

If two or more forces act on the same body, then the acceleration of the body can be written as the vector sum of the individual accelerations produced by each force. The acceleration of the body can be better expressed as the acceleration caused by the resultant force. ..

A body is said to be in motion if its position changes with respect to its surrounding. In order to completely describe the motion of such objects, we need to specify its position. For this, we need to know the position coordinates. In some cases, three position coordinates are required, in some ca..

Torque in Two and Three dimension, then the torque acting on the particle with respect to the origi..

Two Kinds of Electric Charges - You can electrify a glass rod by rubbing it with silk. Suspend such an electrified rod by a silk thread as shown in figure. If you bring another glass rod electrified in the same manner, you will notice that the rods repel each othe..
