Multiple choice

It is difficult to drag a bucket full of water than an empty bucket because

  1. force of friction decreases as we drag a bucket full of water

  2. force of friction increases with the increase of normal force due to increased weight

  3. force of friction increases with the decrease of normal force due to increased weight

  4. force of friction is independent of the weight of the body
