The unit of centripetal acceleration is:
কেন্দ্রাভিমুখ ত্বরণ (Centripetal acceleration)-এর একক কী?
Practice MCQ for SSC, UPSC, RRB Exams
A. m/s²
A. m/s²
B. rad/s
B. rad/s
C. rad/s²
C. rad/s²
D. m/s
D. m/s
Correct Answer: A
সঠিক উত্তর: A
Explanation
ব্যাখ্যা
The unit of
centripetal acceleration
is the same as the unit of any acceleration.
Acceleration is defined as the
rate of change of velocity with respect to time
.
The SI unit of acceleration is
metre per second squared (m/s²)
.
Centripetal acceleration acts towards the
center of a circular path
and is given by the formula:
a = v² / r
Since velocity is in
m/s
and radius is in
m
, the unit becomes:
(m/s)² ÷ m = m/s²
Therefore, the unit of centripetal acceleration is
m/s²
.
কেন্দ্রাভিমুখ ত্বরণ
-এর একক সাধারণ ত্বরণের এককের মতোই।
ত্বরণ হলো
সময়ের সাথে বেগের পরিবর্তনের হার
।
ত্বরণের এসআই একক হলো
মিটার প্রতি সেকেন্ড বর্গ (m/s²)
।
কেন্দ্রাভিমুখ ত্বরণ বৃত্তাকার পথে চলমান বস্তুর ক্ষেত্রে
কেন্দ্রের দিকে ক্রিয়া করে
।
এর সূত্র হলো:
a = v² / r
এখানে বেগের একক
m/s
এবং ব্যাসার্ধের একক
m
হওয়ায়, একক দাঁড়ায়:
m/s²
অতএব, কেন্দ্রাভিমুখ ত্বরণের একক হলো
m/s²
।
