Oh, dude, technically you can't pick up an apple without friction because you need some grip to lift it. Unless you're some kind of wizard with magical powers, then by all means, go ahead and levitate that apple. But for us mere mortals, we need a little friction to get the job done.
No, it is not possible to pick up an apple without friction. Friction is the force that allows us to grip and lift objects, such as an apple, by creating resistance between the surfaces in contact. Without friction, our fingers would not be able to hold onto the apple, making it impossible to pick it up.
No, gravity and contact forces would still act on the apple even without friction, making it impossible to lift it without any resistance.

Friction is necessary to grip the apple firmly enough in our hands to pick it up. Without friction, the apple would slip out of our grasp because there would be no force to counteract the weight of the apple pulling it downwards.
In theory, yes, it is possible to pick up something without friction if the object is in a zero-gravity environment or if the force applied is greater than the force of friction. However, in everyday situations on Earth, it is difficult to pick up something without some level of friction present.
Friction provides the necessary grip and resistance between your fingers and the object's surface to allow you to pick it up. Without friction, your fingers would slide right off the object, making it difficult to grip and lift.
No, you do not need friction to pick up a cup. In fact, reducing friction by applying lubricants can sometimes make it easier to pick up a cup. Gravity and the force exerted by your hand are the main factors involved in picking up a cup.
