begin mathsize 14px style We space know space that space electric space field space is space related space to space potential space as straight E equals negative dV over dx therefore dV equals negative Edx therefore integral subscript 0 superscript 4 dV equals negative integral subscript 0 superscript 4 Edx straight V vertical line subscript 0 superscript 4 equals negative integral 2 xdx therefore straight V subscript 4 equals negative 2 right enclose straight x squared over 2 end enclose subscript 0 superscript 4 therefore straight V subscript 4 equals negative open parentheses 4 squared close parentheses therefore straight V subscript 4 equals negative 16 end style

A parallel-plate capacitor has a plate area of 100c * m ^ 2 and a plate separation of 2.0 cm. has been charged up to 3000 V by a battery. Now, (i) after disconnecting the battery, (ii) keeping the battery connected, the distance between the plates is increased to 5.0 cm intensity of electric field between the plates and the energy of the capacitor. ( epsilon_{0} = 8.85 * 10 ^ - 12 * F * m ^ - 1
