Question

In the figure acceleration of bodies A, B and C are shown with directions. Values b and c are w.r.t ground whereas a is acceleration of block A w.r.t wedge C. Acceleration of block A w.r.t ground is

  1. square root of left parenthesis b plus c right parenthesis to the power of 2 end exponent plus a to the power of 2 end exponent end root    
  2. c minus left parenthesis a plus b right parenthesis c o s invisible function application q    
  3. square root of left parenthesis b plus c right parenthesis to the power of 2 end exponent plus c to the power of 2 end exponent minus 2 left parenthesis b plus c right parenthesis c c o s invisible function application q end root    
  4. square root of left parenthesis b plus c right parenthesis to the power of 2 end exponent plus c to the power of 2 end exponent plus 2 left parenthesis b plus c right parenthesis c c o s invisible function application q end root    

The correct answer is: c minus left parenthesis a plus b right parenthesis c o s invisible function application q
