If a particle moves from point `P(2,3,5)` to point `Q(3,4,5)`. Its displacement vector be

If a particle moves from the point A(1 , 2 , 3) to the point B( 4 , 6 ,9) , its displacement vector be

If a particle moves from the point A(1 , 2 , 3) to the point B( 4 , 6 ,9) , its displacement vector be

Assertion (A) : The position of a particle on a rectangular coordinate system is (3,2,5). Then its position vector be 2hat(i)+5hat(j)+3hat(k) . Reason (R ) : The displacement vector of the particle that moves from point P(2,3,5) to point Q(3,4,5) is hat(i)+hat(j) .

Two forces hati+hatj+hatk N and hati+2hatj+3hatk N act on a particle and displace it from (2,3,4) to point (5,4,3). Displacement is in m. work done is

In a two-dimensional motion of a particle, the particle moves from point A of position vector vecr _(1), to point B of vectors are , respectively, r _(1) =3 and r _(2) =4 and the angles they make with the x axis are theta _(1) = 75^(@)and theta_(2) = 15 ^(@), respectively, then find the magnitude of the displacement vector.

The vector with initial point P(2,-3,5) and terminal point Q(3,-4,7) is :

The vector with initial point P(2,-3,5) and terminal point Q(3,-4,7) is :

A particle is displaced from the point A (-2,0,1) to thp point B(1,3, -3) Find the magnitude of displacement.

The point of application of the force (-2,4,7) is displaced from the point (3,-5,1) to the point (5,9,7). But the force is suddenly halved when the point of application moves half the
