A link `AB` is moving in a vertical plane. At a certain instant when the link is inclined `60^(@)` to the horizontal the point `A` is moving horizontaly at `3m//s`, while `B` is moving in the vertical direction. What is the velocity of `B`?

A

`1/(sqrt(3))m//s`

B

`2sqrt(3)m//s`

C

`sqrt(3)m//s`

D

It is known that there exists a uniform electric field in a certain region. Imagine an incline plane (figure) in the region which is inclined at theta=37^(@) to the horizontal when one moves horizontally along the incline from A to B (AB=1cm), the electric potential decreases by 10V. Similarly, potential at C(AC=1cm) is less than potential at A by 10 V where line AC lies on the incline and is perpendicualr to AB. When one moves vertically up from point A to a point D(AD=1cm), the potential drop by 10 V again. Find the magnitude of the electric field in the region and the angle that it makes with vertical [given sin37^(@)=(3)/(5) ]
