Sand particles drop vertically at the ra...

Sand particles drop vertically at the rate of `2kgs^-1` on a conveyor belt moving horizontally with a velocity of `0.2ms^-1`.
The extra force required to keep the belt moving is

A

0.4 N

B

0.08 N

C

0.04 N

D

0.2 N

Text Solution

Verified by Experts

The correct Answer is:
A
Force required to keep the belt moving `=F `
` F= v =(dm )/( dt) = 0.2 xx 2 = 0.4 N`
