Thanks pathfinder for ur suggestions !!

I'll definitely try this !

Hey !

What does that '/'es represent ???

Basically , what are u trying to show ?

Hey !

Is there no one who can answer this question relating it to physics ?????

Pls reply !!!!!

Hey swaroop ,

I couldn't understand the figure drawn by you !!!

Pls explain !!!!!

Hey nikhil ,

the correct answer is mg/cos(theta) . Also , the 'a' (acceleration) used by sen_holmes is not provided in the question !!!!!!

Hey mayur ,

what u said is right . Also , I found in a book that value of friction's cofficient generally lies between 0.05 and 1.5.

Anyways , thnks for giving the answer !!!

Hey pearlypeeble , yes , this is the right answer . But , i want to know why cant we resolve weight force ???Why only normal force ?

Pls explain as soon as possible !!!

Hey all ,

This is a physics que , and u all are answering biologically .If possible , pls give me a answer relating it to physics !!!!!!!!!!!!

Two objects A and B are thrown upward simultaneously with the same speed . The mass of A is greater than B . Suppose air resistance is equal on both bodies .

(a) The two bodies will reach the same height

(b) A will go higher

(c) B will go higher

 

Solve - 

A system consists of a cart having mass M and a block of mass m , attached to a spring of a constant k.The block is kept on the cart . Initially , the cart and the block are at rest and the spring is streched through a distance x , when the system is released . Find the time periods of the two SHM's and the amplitudes of the SHM of the block and of the cart as seen from the road .

For figure , pls consult HC verma , Ch- SHM , pg-254 , que -30 (acc. to my book )

Solve -

A block of mass m is placed on a smooth wedge of inclination theta . The whole system is accelerated horizontally so that the block does not slip on the wedge . Find the magnitude of the force exerted by the wedge on the block .

Pls give the detailed solution !!!

Hey all ,

for most of the surfaces used in daily life , the friction cofficient is less than 1 . Is it always necessary that the friction cofficient is less than one ??

If yes , then why ? And if no ,then what can be its maximum value ?

 

Hi ,

If possible , pls send me the papers . I will be highly oblidged !!!

My email id is callumang@gmail.com .

Thank you !!!!!

Thanks for the advice titun !!!
