Assertion: Where a mole of electron is transported across a potential difference of `1V` from positive electrode to negative electrode, then work done

Monjur Alahi

Assertion: Where a mole of electron is transported across a potential difference of `1V` from positive electrode to negative electrode, then work done is `-96500J` .
Reason: Work done due to transportation of electrons depends on the product of potential difference between the two points and amount to charge carried.
A. If both the assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both the assertion and reason are true but reason is not the correct explantion of the assertion.
C. If the assertion is true but reason is false.
D. If assertion is false but reason is true.

Find the work done when a point charge of 2.0 pc is moved from a point at a potential of -10 V to a point at which the potential is zero.

VA = -10V, VB = 0, q = 2 × 10-6 C To Find: Work done (W) Formula: VBA = \(\frac{W}{q}\) Calculation: From formula, W = VBA × q = (VB – VA) × q = (0 + 10) × 2 × 10-6 = 20 ×...

Find the common difference of an A.P if \( t_{18}-t_{14}=3 L \). If \( 3+k, 18-k, 5 k+1 \) are in A.P, then find \( k \). If \( p \) and \( q \) are positive integers, then we write \( p=a^{2} b^{3} \) and \( q=a^{3} b \) if \( a \), \( b \) are numbers, then verify that L.C.M of \( (p, q) \times \) H.C.F of \( (p, q)=p q \).

t18=t1+17×d t14=t1 +13×d solving the two equtaions, t18-t14= 4d subtisting 4d=32 =  d=8
