Question

multiple choice question
what is the weight of a 5.0 kg box if the gravitational strength is 9.8 n/kg?
0.51 n
2.0 n
4.8 n
49 n

Explanation:

Step1: Recall the formula for weight

Weight \(W = m\times g\), where \(m\) is mass and \(g\) is gravitational strength.

Step2: Substitute the given values

Given \(m = 5.0\space kg\) and \(g=9.8\space N/kg\). Then \(W=5.0\times9.8\).

Step3: Calculate the product

\(5.0\times9.8=(5\times9)+(5\times0.8)=45 + 4=49\)

Answer:

49 N
