Question

The fiqure below shows a bead sliding without friction along a curved wire in a vertical plane The bead slides starting from rest at position C on the frictionless wire. The direction of the gravitational field is in the -y direction (toward the bottom of the page) Equal to The acceleration in the x-direction at D is True True True The velocity at H equals the velocity at A. Equal to The speed at H is the speed at A. Greater than The speed at D is.. the speed at H zero. The acceleration at H is zero. The acceleration in the y-direction at D is... zero. Submit Answer Incorrect. Tries 4/6 Previous Tries

Explanation / Answer

1

Equal to 0.

since the the accelelarion due gravity is in y diection and due to centripetal force is also in y direction.

2

False

the accelelarion due gravity is in y diection and due to centripetal force is also in y direction so net acceleration is not zero

3

not equal to zero

since the the accelelarion due gravity is in y diection and due to centripetal force is also in y direction.

4

true

since both are at same height so velocity at same height must be equal in order to have same kinetic energy

5

equal to

same as above reason

6

greater than

since d is at lower point so have less potential energy so to conseve total energy velocity must be greater at d
