Force is a vector quantity because it has:
বল (Force) একটি ভেক্টর রাশি কারণ এতে রয়েছে—
Practice MCQ for SSC, UPSC, RRB Exams
A. Only magnitude
A. কেবল মান
B. Only direction
B. কেবল দিক
C. Both magnitude and direction
C. মান ও দিক উভয়ই
D. Neither magnitude nor direction
D. মান ও দিক কোনোটিই নয়
Correct Answer: C
সঠিক উত্তর: C
Explanation
ব্যাখ্যা
Correct Answer: C) Both magnitude and direction
A
vector quantity
is defined as a physical quantity that has both
magnitude and direction
.
Force
not only has a certain
strength (magnitude)
but also acts in a
specific direction
.
The effect of a force on an object depends on
how strong the force is
and
in which direction it is applied
.
Because force satisfies both these conditions, it is classified as a
vector quantity
.
Quantities having only magnitude are called
scalar quantities
.
সঠিক উত্তর: C) মান ও দিক উভয়ই
ভেক্টর রাশি
হলো এমন ভৌত রাশি যার
মান এবং দিক উভয়ই থাকে
।
বল
-এর একটি নির্দিষ্ট
মান
রয়েছে এবং এটি একটি
নির্দিষ্ট দিকে
ক্রিয়া করে।
কোনো বস্তুর উপর বলের প্রভাব নির্ভর করে
বল কতটা শক্তিশালী
এবং
কোন দিকে প্রয়োগ করা হয়েছে
-এর উপর।
এই দুটি বৈশিষ্ট্য থাকার কারণে বলকে
ভেক্টর রাশি
বলা হয়।
যেসব রাশিতে কেবল মান থাকে, সেগুলোকে
স্কেলার রাশি
বলা হয়।
