Question

1) For the radii of 17 cm and 19cm, calculate the value of (delta) ?x. Remember that the circumference of the circle is divided into 36 equal parts. 2) If an expierment contained no errors, how should Fc and Fmag relate to one another? Explain your answer. 1) For the radii of 17 cm and 19cm, calculate the value of (delta) ?x. Remember that the circumference of the circle is divided into 36 equal parts. 2) If an expierment contained no errors, how should Fc and Fmag relate to one another? Explain your answer.

Explanation / Answer

1) l1 = R1(2(pi)R1/36) (perimeter of the circle subtends 2(pi) angle at the centre) = 17 cm *(2(pi)17 cm /36) = 50.439 cm l2 = R2(2(pi)R2/36) (perimeter of the circle subtends 2(pi) angle at the centre) = 19 cm *(2(pi)19 cm /36) = 63.006 cm DeltaX = 63.006 cm - 50.439 cm = 12.568 cm 2) If there are no errors, then the centripetal force (or central force) Fc will be related to the magnetic force Fmag by the relation Fmag = Bqv = Bqv*vm/R * R/mv = BqR/mv * mv^2/R = BqR/mv * Fc
