Question

A skateboard is pushed up a hill with a 90 N force to the left and experiences a gravitational force of 100 N to the right. (A) Will accelerate to the left (B) Will accelerate to the right (C) Will not accelerate

Answer 1

Since the 100 N to the right is greater than the 90 N, it will accelerate to the right.

Answer 2

Answer: The correct answer is Option B.

Explanation:

Balanced force is defined as the forces that gets cancelled out when equal forces are acting in the opposite direction. The net force on the system comes out to be 0.

Unbalanced force is defined as the forces that does not get cancelled out because unequal forces act on the system in opposite direction. The motion of the object is in the direction of net force.

According to the question:

A skateboard is pushed up a hill, the force applied on it is 90 N to the left.

The gravitational pull acting in the right on the skateboard is 100 N.

Net force acting on the object = 100- 90 = 10 N (acting in the right direction)

Hence, the correct answer is Option B.
