Point 1 is the one
hope it’s Helpful :)

Answer 2

Cup and bob" viscometer is not a one point viscometer but can be used for same purpose​

Explanation:

• Cup and bob" viscometer is used to measure the torque which is required to rotate a disk or bob in a fluid at a known speed.
• These viscometers work by defining the exact volume of a sample which is to be sheared within a test cell.
• The torque required to achieve rotational speed can be measured and plotted with the help of this viscometer.
• They measure the torque which is required to rotate a disk or bob in a fluid at a known speed.
• "Cup and bob" viscometers work with the exact volume of a sample which is to be sheared within a test cell.
