Here, T is the tension in the string. Now, suppose A is further displaced by a distance x from its mean position and v be its speed at this moment. Then B lowers by and speed B at this instant will...

Now, as the pulley is massless, this force is equal to extra 2T or T = . this is also the restoring force of the mass. Hence (c) In this situation if the mass m moves down a distance x from...

Question - 5. A ball is suspended by a string by length 'd' at point O. on an inclined wall angle and replaced. Find the period of ascillation if (1) < ; (2) > . Consider l = 1 for...

Here Generalising the result : Hence Combining of SHM's : The resultant motion of a particle, if 2 forces which produce SHM are applied over it, is a combination of the two SHM's. The two...

* Note :- (K.E.) + (P.E.) = Const. = So we can say that if Dumb Question :- What is the relevance of Mechanical energy being constant hare ? Solution :- Suppose the system i like : When at...

Now suppose the ball started from a point after than = 0 say then : So here = phase constant # illustration :- Two SHM's of amplitude with initial

Introduction Natures follows periodicity. The day and night, fhe and death everything is repetitive. Periodic motion is the motion is the motion that repeats itself after a fixed period of time....
