Question

Velocity of three particles A, B and Cvaries with time t as,  = (2t  + 6  ) m/s,  = (3  + 4  ) m/s and  = (6  + 4t  ). Regarding the pseudo force match the following table –
Column IColumn II(i) On A as observed by B[A] Along positive x-direction(ii) On B as observed by C[B] Along negative x-direction(iii) On A as observed by C[C] Along positive y-direction(iv) On C as observed by A[D] Along negative y-direction[E] zero

The correct answer is A. Step 1: Identify the direction of the pseudo forces acting on each particle as observed from another particle using their velocity equations.For A as observed by B, since B has a higher velocity, the pseudo force on A will be towards the positive x-direction.For B as observed by C, since C is moving faster than B, the pseudo force will be acting on B towards the negative x-direction.For A as observed by C, as C moves faster than A, the pseudo force on A will be in the positive y-direction.For C as observed by A, as A is moving slower than C, the pseudo force will act along the negative y-direction.Therefore, the matches are: (i) - [A], (ii) - [B], (iii) - [C], (iv) - [D]. Thus, the correct answer is A.
