Frequency of oscillation of a body is 6 Hz when force `F_(1)` is applied and 8 Hz when `F_(2)` is applied . If both forces `F_(1)` and `F_(2)` are applied together, then find out the frequency of oscillation.

On a smooth horizontal tanle, a sphere is pressed by blocks A and B by forces F_(1) and F_(2) respectively (F_(1)gtF_(2)) exactely normal to the tangent at the point of contact of blocks and sphere. A force F is applied on the sphere diameter OP , which is line of action of forces F_(1) and F_(2) . the sphere moves out of blocks A and B . find minimum value of F . the coefficient of friction is mu at all contancts.

A wire has an elongation of 0.04m when a force F is applied on it . Now its length & diameter are double and same force F is applied on it. Find new elongation in the wire

A yo-yo is resting on a perfectly rough horizontal table . Forces F_(1), F_(2) and F_(3) are applied seqarately as shown . The correct statement is

If force F is applied on a body and it moves with a velocity v, the power will be

When a force F acts on a body of mass m the acceleration product in the body is a . If three equal forces F_(1)=F_(2)=F_(3)=F act on the same body as shown in figure the acceleration produced is

When tuning forks A and B are sounded together, 20 beats are produced in 8 second between them. (i.e. beat frequency is (20)/(8) =2.5 Hz). Now, when some wax is applied on one of these tuning forks, 32 beats are produced in 8 s. If frequency of that fork on which wax is not applied is 512 Hz then find frequency of another tuning fork, before and after applying wax.
