Question

Statement I : Graph of y = tan x is symmetrical about origin
Statement II : Graph of y equals sec squared invisible function application x is symmetrical about y-axis

  1. If both (A) and (R) are true, and (R) is the correct explanation of (A) .    
  2. If both (A) and (R) are true but (R) is not the correct explanation of (A) .    
  3. If (A) is true but (R) is false.    
  4. If (A) is false but (R) is true.    

The correct answer is: If both (A) and (R) are true, and (R) is the correct explanation of (A) .


    y = tan x is odd function so must be symmetrical about origin & y equals s e c to the power of 2 end exponent invisible function application x is decretive of y = tan x so it must be even imply symmetrical about y-axis or vice-versa

    As shown a block of mass M blankis lying over rough horizontal surface. Letblank mu be the coeeficient of kinetic friction between the two surfaces in contact. The force Of friction between the block and horizontal surface is given by
    F equals mu R equals mu M g (because R equals M g right parenthesis
    To move the block without acceleration, the force (P)required will be just equal to the force of friction , ie ,
    P equals F equals mu R
