Question
Fusion reaction take place at high temperature because$:$
✓
Answer
Fusion reaction takes place at temperature about $10^7K.$
It requires this high temperature so that nucleus are moving rapidly,so that they have high kinetic energy and can come together by overcoming repulsion between them.

E denotes electric field in a uniform conductor, I corresponding current through it, $v_d$ drift velocity of electrons and P denotes thermal power produced in the conductor, then which of the following graph is incorrect
→Two metallic plates $A$ and $B,$ each of area $5 ´ 10^{–4}m^2$ are placed parallel to each other at a separation of $1 \ cm$. Plate $B$ carries a positive charge of $33.7\ pc$. A monochromatic beam of light, with photons of energy $5\ eV$ each, starts falling on plate $A$ at $t = 0,$ so that $10^{16}$ photons fall on it per square meter per second. Assume that one photoelectron is emitted for every $10^6$ incident photons. Also assume that all the emitted photoelectrons are collected by plate $B$ and the work function of plate $A$ remains constant at the value $2\ eV$. Electric field between the plates at the end of $10$ seconds is
