Answer given question
Two identical conducting spheres carrying different charges attract each other with a force \(F\) when placed in air medium at a distance \(d\) apart. The sphere are brought into contact and then taken to their original positions. Now, the two spheres repel each other with a force whole magnitude is equal to that of the initial attractive force. The ratio between initial charges on the spheres is
(a) \(-(3 + \sqrt 8)\) only
(b) \(-3 + \sqrt 8\) only
(c) \(-(3 + \sqrt 8) \) or \((-3 + \sqrt 8)\)
(d) \(+ \sqrt 3\)
(e) \(- \sqrt 8\)

In what way the reaction will occur in case of addition of alkenes, in the presence of H2SO4, specifically at 80 degree Celsius temperature ? Is it the same as shown in the video no. 8 of chapter Hydrocarbons ? (We have got a product with 7 carbons, whereas we have only 6 carbons on the left side of the reaction.) If not, then what will be the actual product in that case ?
