A famous relation in physics relates ‘moving mass’ m to the ‘rest mass’ m0 of a particle in term of its speed v and the speed of light, c [ This relation first arose as a consequence of special relativity due to Albert Einstein]. A boy recalls the relation almost correctly but forgets where to put the constant c. He writes: m= m_0/〖(1- v^2)〗^(1/2) NCERT Solution

A book with many error contains four different formulas for the displacement y of a parties undergoing a certain periodic motion : (a) y = a sin 2π t/T (b) y = a sin vt (c) y = (a/T) sin t/a (d) y = (a √2 (sin 2π t/T + cos 2π t/T) (a = maximum displacement of the particle, v = speed of the particle, T = time-period of motion), Rule out the wrong formulas on dimensional grounds.

A physical quantity P is related to four observables a, b, c and das follows: P = a3b 2 / √(c ) d The percentage error of measurement in a, b, c and d are 1% 3% 4% and 2%, respectively. What is the percentage error in the quantity p? If the value of p calculated using the above relation turns out to be 3.763, to what value should you around off the result? NCERT Solution
