for angle $ and pi - $ range is same u all know
but
T1 (for $) + T2 (for pi - $ ) = 2R/g
H1 (for $) + H2(for pi - $ ) = Hmax.
H1 . H2 = R^2/16

min. no. of equal vectorsthat can give zero resultant is 2
" " " un= " " " " " " " 3
and in case of unequal vectors all the three vectors must form a triangle

two vectors give resultant = to either of them wen angle b/w them is 120 degress
mag. of vector addition = mag. of vector subtraction wen angle b/w them is 90 degrees
mag of dot product = mag. of cross product wen angle is 45 degress

projectile thrown parallel to hor.
T = {2H/g}^1/2
R =u (2H/g)^1/2
K.E of projectile at the top
K(top) = Kcos^2$

Suppose we slide a pearl thro a rod and the coeff of friction is #, then the max constant angular vel with which the rod can be rotated so that the bead doesnot slide is given as: w= (#g/l) where l is the length of the rod....
