find the distance between two proton if the repulsive force is equal to mass of proton
1 Answer
Abhishek Saharia
Mass of one proton= 1.67x10-27.
Force between two proton(F)= 9x109xqxq/r2.
q= charge of one proton= +1.6x10-19
r= distance between the two proton.
A/Q,
F= 1.67x10-27
Therefore, 9x109x1.6x10-19x1.6x10-19/r2 = 1.67x10-27.
r2= 13.8x10-2.
Thus r = 3.715x10-1m.
Thus, the distance between the two protons is 0.3715m or 37.15 cm.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
