derive the expression for the radius and frequency of a charge describing in uniform circular motion in a uniform magnetic field??​

Answer»

If r is the RADIUS of the CIRCULAR path of a PARTICLE, then a force of m v2/r, acts perpendicular to the path towards the centre of the circle, and is called the centripetal force. If the velocity v is perpendicular to the magnetic field B, the magnetic force is perpendicular to both v and B and acts like a centripetal force. It has a magnitude q v B. Equating the two expressions for centripetal force, m v2 /r = q v B, which gives r = m v / qB --------- (1) for the radius of the circle described by the charged particle. The larger the momentum, the larger is the radius and bigger the circle described. If W is the angular frequency, then v = ω r. So, ω = 2πυ = q B/ m ---------- (2) which is independent of the velocity or energy . Here N is the frequency of rotation. The independence of n from energy has important application in the design of a cyclotron. The time taken for one revolution is T= 2π/ω = 1/υ. If there is a component of the velocity parallel to the magnetic field (denoted by v||), it will make the particle move along the field and the path of the particle would be a helical one. The distance moved along the magnetic field in one rotation is called pitch p. Using Eq. (2) we have p = v||T = 2πm v|| / q B --------- (3) The radius of the circular component of motion is called the radius of the helix.

Structure of the modern periodic table​

Answer»

the modern periodic table, the ELEMENTS are arranged in the order of their increasing atomic number. In the modern periodic table, there are SEVEN horizontal rows called PERIODS and eighteen vertical columns (1 to 18) called groups. The arrangement of the periods and groups results in formation of BOXES.

Answer»

tional force between two bodies is defined as GMm/R²Case1Gravitational force = GMm/R²in this CASE ACTUAL mass of bodies are takenCase2In this case masses of bodies are REDUCED to half.Gravitational force' =GM½m½/R²Gravitational force'=GMm/4R²Hence if we reduce mass to half the gravitational force is reduced to ¼th of its initial VALUE
