Two identical blocks of same masses are placed on a fixed wedge as shown in figure. Coefficient of friction between all the contact surfaces is u. Choose the correct alternative (A) For motion at any surface, thetha≤ tan-¹(u). (B) Acceleration of block A will be more than acceleration of block B in downward direction. (C) Acceleration of block A will be less than acceleration of block B in down ward direction (D) Two blocks A and B move with same acceleration. ​
