Question

he foure below shows a bead sliding without friction along a curved wire in a vertical plane. owara heidostotarirg fron rest at position D on the frictionless wire. The direction of the gravitational field is in the -y direction ue B The velocity at C equals the velocity at H Equa to The speed at H is. the speed at C. Less than The speed at H is . the speed at A. Fase The acceleration at H is zero. Greater than D The acceleration in the y-direction at A is Equal toThe acceleration in the x-direction at A is 113 zero. zero 157-80810 Tries 5/30 BBBBBB

Explanation / Answer

Statement - 1 -

False (Explanation - Velocity is a vector which includes magnitude as well as direction. Magnitude of velocity at points C and H are equal but its directions are different. So velocity at these two points cannot be equal)

Statement - 2 -

equal to (Explanation - as mentioned above)

Statement - 3 -

less than (Explanation - at point H, the bead has more potential energy as point H is at a higher level than point A so its speed is less)

Statement - 4 -

False (acceleration at H = g = 9.8 m/s^2)

Statement - 5 -

Greater than (acceleration in y - direction = g = 9.8 m/s^2)

Statement - 6 -

Equal to (acceleration in x - direction = 0)
