Please answer the below question
Assertion : An observer is moving due east and wind appears him to blow from north. Then the actual direction of air blow is towards south-east.
Reason : Because \(\vec V_R = \vec V_A - \vec V_M \) where \(\vec V_R\) is the relative velocity of wind with respect to man, \(\vec V_A =\) actual velocity of wind (w.r.t. ground) and \(\vec V_M =\) velocity of man w.r.t. ground.
(a) A
(b) B
(c) C
(d) D

plz solve this problem
The acceleration due to gravity g' at height h from the surface of radius R is given by \(g' = \frac {gR^2}{(R + h)^2}\)
where g is the acceleration due to gravity on the earth's surface. Find out the value of g' using the binominal theorem, if \(h<
