प्रतिबल - प्रति एकक क्षेत्रफळ एखाद्या वस्तूवर कार्य करणारे बल म्हणून प्रतिबलाची व्याख्या केली जाते. हे N/m2 म्हणून मोजले जाते.
प्रतिबल \( = \frac{{Force}}{{Area}}\) ----(1)
बल = वस्तुमान \(\times\) प्रवेग
⇒ F = ma
⇒ [F] = [MLT-2]
आणि क्षेत्रफळ, [A]= [L2]
ही मूल्ये समीकरण (1) मध्ये टाकून आपल्याकडे आहे;
प्रतिबल = \( \frac{{\left[ {ML{T^{ - 2}}} \right]}}{{\left[ {{L^2}} \right]}}\)
⇒ प्रतिबल = \( \left[ {M{L^{ - 1}}{T^{ - 2}}} \right]\)
म्हणून, पर्याय 2) योग्य उत्तर आहे.
