As shown in the figure, a particle of mass 10 kg is placed at a point A. When the particle is slightly displaced to its right, it starts moving and reaches the point B. The speed of the particle at B is x m/s. (Take `g=10 m//s^2` ) The value of 'x to the nearest integer is

A particle is placed at the point "A" of a frictionless track "ABC" as shown in figure.It is gently pushed towards right.The speed of the particle when it reaches the point "B" is: (Take g=10m"/"s^(2)

As shown in figure a dust particle with mass m = 5.0 × 10–9 kg and charge q0 = 2.0 nC starts from rest at point a and moves in a straight line to point b . What is its speed v at point b?

The projectile motion of a particle of mass 5g is shown in the figure The initial velocity of the particle is 5sqrt2ms^(-1) and the air resistance is assumed to be negligible. The magnitude of the change in momentum the points A and B is x xx 10^(-2) kgms^(-1) . The value of x, to the nearest integer is..

A particle of mass 200 g is moving in a circle of radius 2 m. The particle is just looping the loop. The speed of the particle and the tension in the string at highest point of the circule path are (g=10ms^(-2))

A particle is moving in a verticalcircle such that the tensionin the string at the topmost point B is zero.Theaccelerationof theparticle at point A is (g=10m//s^(2))

A person is swimming with a speed of 10 m/s at an angle of 120° with the flow and reaches to a point directly opposite on the other side of the river. The speed of the flow is 'x m/s. The value of 'x to the nearest integer is_________.
