A jet of water hits a flat stationary pl...

A jet of water hits a flat stationary plate perpendicular to its motion. The jet ejects `500g` of water per second with a speed of `1m//s`. Assuming that after striking, the water flows parallel to the plate, then the force exerted on the plate is

A

(a) `5N`

B

(b) `1.0N`

C

(c) `0.5N`

D

(d) `10N`

Text Solution

Verified by Experts

The correct Answer is:
C
`v_i=1m//s`, `v_f=0`
`|F|=|(Deltap)/(Deltat)|=((Deltam)/(Deltat))(v_i-v_f)`
`=0.5xx1=0.5N`

An electron (charge = e, mass = m) is projected horizontally into a uniform electric field produced between two oppositely charged parallel plates, as shown in figure. The charge density on both plates is +- sigma C//m^2 and separation between them is d. You have to assume that only electric force acts on the electron and there is no field outside the plates.
