Question

question 5 of 25 a jar of mass 2.1 kg sits on a table. what is the normal force acting on the jar? a. 2.1 n b. 33.1 n c. 5.3 n d. 20.6 n

Explanation:

Step1: Identify normal force condition

Normal force equals weight for stationary object on table.

Step2: Calculate weight

Weight \( W = m \times g \), \( m = 2.1 \, \text{kg} \), \( g = 9.8 \, \text{m/s}^2 \).
\( W = 2.1 \times 9.8 = 20.58 \, \text{N} \approx 20.6 \, \text{N} \).

Answer:

D. 20.6 N
