Answer 1

$\huge\mathcal{Answer:}$

No, is impossible to open a pen ca with one finger because two fingers produce enough frictional force to produce required amount of torque. if we try to open the pen cap with one finger we can't succeed as one finger alone doesnt produce enough frictional force to produce required amount of torque

Answer 2

Answer:

Yes it's possible but you have to exert more pressure
