  • A cyclotron is a device used by scientists to study properties of subatomic particles. Light weight charged partcles are deposited at high speed. When charged particle reaches desired speed, a mag. Field keeps it moving in a circle at constant speed. A mag. field pointing inwards keeps a charged particle in anticlockwise direction at constant speed. the mag . force provides centripetal force F_(m)=qvB . Beacuse of this magnetic force, its frequency v is (qB)/(2 pi m) Which of following particles would not work in a cyclotron ?

    A
    `Li^(+)`
    B
    Li atom
    C
    `Li^(-)`
    D
    All of the above

    A survey was conducted by a group of students as a part of their environment awareness programme, in which they collected the following data regarding the number of plants in 20 houses in a locality. Find the mean number of plants per house. Which method did you use for finding the mean, and why?

    A natural occurring class of plant hormones cytokinins has been found to help increase cotton yields during drought conditions. It has been observed that young cotton seedlings have small root system, making it difficult for them to reach available soil water. Cytokinins assists the young plants in water stress defences, promoting the plant to quickly build a bigger root system to access deep soil mosture. To be effective this phytohormone should be at an early stage of development. Which hormone is synthesized at the shoot - tip of plant body ?

    Let us list some of the factors, which could possibly influence the speed of wave propagation: (i) nature of the source. (ii) direction of propagation. (iii) motion of the source and/or observer. (iv) wavelength. (v) intensity of the wave. On which of these factors, if any, does (a) the speed of light in vacuum, (b) the speed of light in a medium (say, glass or water), depend?
