The positively charged particle is _______

Ten positively charged particles are kept fixed on the x-axis at points x=10cm, 20cm, 30cm, …, 100cm. The first particle has a charge 1.0xx 10^(-8)C , the second 8xx10^(-8) C, the third 27xx10(-8) C and so on. The tenth particle has a charge 1000xx10^(-8)C. find the magnitude of the electric force acting on a 1 C charge placed at the origin.

Solve the following crossword with the help of the given clues. The negative electrode is an electrolytic cell, toward which positively charged particles are attracted.

The force on a charged particle due to electric and magnetic fields is given by vecF=qvecE+qvecvXvecB . Suppose vecE is along the X-axis and vecB along the Y-axis. In what direction and with what minimum speed v should a positively charged particle be sent so that the net force on it is zero?

(I) Cathode rays produce heat, when allowed to fall on matter. (II) Cathode rays produce X-ray, when allowed to fall on material of high atomic weight. (III) Cathode rays are positively charged particles (IV) Cathode rays ionize the gas.

A positively charged particle projected towards east is deflected towards north by a magnetic field. The field may be

Suppose all the electrons of 100 g are lumped together to form a negatively charged particle and all the nuclei are lumped together to form a positively charge particle. If these two particles are placed 10.0 cm away from each other, then the force of attraction between them. Compare it with your weight.
