A small steel ball falls through a syrup at a constant speed of 1.0 m/s. If the steel balls is pulled upwards with a force equal to twice its effective weight, how fast will it move upwards ?

A

`10 cm//s`

B

`20 cm//s`

C

`5 cm//s`

D

`-5 cm//s`

Text Solution

Verified by Experts

The correct Answer is:
