Question : 11 of 54

Marks: +1, -0

List I describes four systems, each with two particles A and B in relative motion as shown in figure. List II gives possible magnitudes of then relative velocities (in ms−1 ) at time t=‌

List-I

List-II

(I)

A and B are moving on a horizontal circle of radius 1m with uniform angular speed ω=1‌rad‌s−1. The initial angular positions of A and B at time t=0 are θ=0 and θ=‌

respectively.

(P)

‌

√3+1

(II)

Projectiles A and B are fired (in the same vertical plane) at t=0 and t=0.1s respectively, with the same speed v=‌

ms−1 and at 45∘ from the horizontal plane. The initial separation between A and B is large enough so that they do not collide, (g=10ms−2).

(Q)

‌

(√3−1)

(III)

Two harmonic oscillators A and B moving in the x direction according to xA=x0‌sin‌

and xB=x0‌sin(‌

) respectively, starting from t=0. Take x0=1m,t0=1s.

(R)

√10

(IV)

Particle A is rotating in a horizontal circular path of radius 1m on the xy plane, with constant angular speed ω=1‌rad‌s−1. Particle B is moving up at a constant speed 3ms−1 in the vertical direction as shown in the figure. (Ignore gravity.)

(S)

√2

(T)

√25π2+1
