Acceleration of a particle which is at rest at ` x=0` is `vec a = (4 -2 x) hat i`. Select the correct alternative (s).

The relation between acceleration and distance is is : a= ( 4-2x) .Select the correct alternative (s) .

A particle of mass 2kg moves under a force given by vec(F)=-(8N//m)(xhat(i)+yhat(j)) where hat(i) and hat(j) are unit vectors in the x and y directions. The particle is projected from a point on x axis at x=a in xy plane with an initial velocity vec(v)=v_(0)hat(j) . Select correct statement (s). The particle will move in

The velocities of two particles A and B of same mass are vec V_A = a hat i and vec V_B = b hat j where a and b are constants. The acceleration of particle A is (2 a hat i+ 4 b hat j) and acceleration of particle B is (a hat i- 4 b hat j) (in m//s^2) . The centre of mass of two particle will move in :

Velocity and acceleration vectors of a charged particle moving in a magnetic field at some instant are vec(v)=3hat(i)+4hat(j) and vec(a)=2hat(i)+xhat(j) . Selcet the wrong alternative.

A particle of mass 2kg moves under a force given by vec(F)=-(8N//m)(xhat(i)+yhat(j)) where hat(i) and hat(j) are unit vectors in the x and y directions. The particle is projected from the origin in xy plane with an initial velocity vec(v)=(3m//s)hat(i)+(4m//s)hat(j) . Select correct statement(s).
