सर्वपल्ली राधाकृष्णन एक महान दार्शनिक और शिक्षक थे और शिक्षा में उनका काफी लगाव था, इसलिए सम्पूर्ण भारत में सरकार द्वारा शिक्षा के क्षेत्र में अच्चा करने वाले छात्रों को पुरस्कार दिया जाता है. ऐसा कहा जाता है कि गुरु अर्थार्त शिक्षक के बिना सही रास्तों पर नहीं चला जा सकता है. वह मार्गदर्शन करते है. तभी तो शिक्षक छात्रों को अपने नियमों में बांधकर अच्चा इंसान बनाते हैं और सही मार्ग प्रशस्त करते रहते है. इसलिए यह कहना गलत नहीं होगा कि जन्म दाता से बढकर महत्व शिक्षक का होता है क्योंकि ज्ञान ही इंसान को व्यक्ति बनाता है, जीने योग्य जीवन देता हैं.

Given force of 1200 n acts on the surface of area 10 cm square, here force is same as thrust which is equal to 1200 N, Area = 10 sq cm
We need to convert area into sq m
So 10 sq cm = 10 cm x cm = 10 cm2
= 10 / 100 x 100 = 1 / 1000 m^2 = 0.001 m2
Pressure = Force / unit area
= 1200 / 0.001
= 1200 x 1000
Pressure = 12 x 105 Pascals
