Answers : (1)


let the angel made by string with verticle is @

normal reaction is perpendicular to wall and weight

tension is making angle of 90+@ with normal reaction and 180-@ with weight

now applying sune rule

   w/sin(90+@) = T/sin90 = N/sin(180-@)


now find cos@ in terms of L and R put put in eq 1

a block of mass m is held against a rough vertical wall by pressing in with a finger if u is the coeffcieng of friction between block and wall and g is the acceleration due to gravity...
This time normal force = m*a f = u*ma or = u*mg that would be the only force would be left for balancing the forec applied by the finger to the block against the wall.

a cricket ball is thrown at a speed of 28m/s in a direction 30*( 30 degrees) above the horizontal .Calculate its maximum height.
Here, velocity of projection, u = 28 m/s. Angle of projection, = 30 ০ . We have, maximum height attained by a projectile, So, the maximum height attained by the ball is 20 m. THANKS

Is angular acceleration about any point on a rotating rigid body same? If so what is the value of it for a rod of length with a force of M*g acting on the centre and M*g/2 acting on one end...
net moment = I * a where a is the angular accln. Therefore, moment about centre = Mg*l/2 = Ml^2/12 * a Get the value of a Hence.
