alleryএটা শিশুৱে এখন সমতল দাপোনৰ পৰা 1.5 মিটাৰ দূৰত থিয় হয়, তাৰ পিছত 0.5 মিটাৰ তাৰ ফালে আগবাঢ়ি যায়। শিশুৰ পৰা ছবিলৈ নতুন দূৰত্ব কিমান?
A3.0 m
B1.0 m
C0.5 m
D2.0 m
Answer & Solution
Correct answer: D. 2.0 m
তাৰ পিছত শিশুটি আইনাখনৰ পৰা 1.0 মিটাৰ দূৰত থাকে আৰু ছবিখন 1.0 মিটাৰ পিছফালে থাকে, যাৰ ফলত 2.0 মিটাৰ পৃথকীকৰণ পোৱা যায়।
