Question

When a cup is placed on a table, which force prevents the cup from falling to the ground? A. gravitational force B. normal force C. resistance force D. tension force

Answer 1

its B... normal force

Answer 2

here normal force will balance the weight of cup which will prevent it from falling

B. normal force

Step-by-step explanation:

When cup is placed on the table then there will be two forces on the cup

1). Normal force due to table which will be perpendicular to the table and acting upwards

2). gravitational force or weight of the cup which acts perpendicular downwards

now since the cup is at rest so net force on the cup must be balanced

so we can say

`F_g - F_n = 0`

so here we will have

`mg - F_n = 0`

so here normal force will balance the weight of cup which will prevent it from falling
