Real questions that test this
खालील वाक्ये लक्षात घ्या. (a) कणाची वेधनशक्ती (सामर्थ्य) ही त्याच्या वस्तुमानाच्या व्यस्त प्रमाणात असते. (b) अल्फा कणाची वेधनशक्ती (सामर्थ्य) ही बीटा कण्याच्या वेधन शक्ती (सामर्थ्य) पेक्षा कमी आहे. खालीलपैकी कोणते विधान वरील वाक्यांची परिस्थिती योग्य रीत्या दाखवते? Consider the following statements : (a) Penetrating power of a particle is inversely proportional to its mass. (b) Penetrating power of α(alpha) particle is less than that of β(Beta) particle. Which one of the following gives a correct picture about the above statements ?
Penetrating power is inversely proportional to mass (heavier particles interact more and lose energy faster). Since alpha particles are much heavier than beta particles, their penetrating power is less than that of beta particles.
